ProtoArc EM01 NL Wireless Bluetooth Trackball Mouse Adjustable Angle

I've been using this daily now for almost a year and I find it much more comfortable to use and easier on the wrist than a regular mouse. I bought it to try because I was feeling strain from clicking and holding the middle mouse button whilst also moving the mouse which you have to do a fair bit in Blender and other 3D software. This type of mouse solved my problem as I'm no longer fighting my own grip. It's also a space saver as you no longer need to move the mouse around the desk. This is my first trackball mouse but I quickly adapted and within a couple of days I was just as accurate at moving the ball as I was pointing with a regular mouse. I don't have much to compare to but the build quality feels solid. I've not had any connectivity issues or issues with glide or smoothness, and it works well switching between different devices. The battery lasts a few months between charges and you can use it while charging too. The buttons are all nice to click in both orientations (flat or tilted) and the sensitivity is just set once and forget. You do have to pop the ball out to remove dust occasionally but it appears that's just expected maintenance with this kind of mouse. There's a handy hole you can push something through to help with popping it out. I'm really happy with this purchase and it has become part of my every day setup. I'm not sure how it weighs up against more expensive models but I'm happy enough and not looking to upgrade any time soon.

I would say a good trackball device. This was a quick purchase because my logi mx buttons are now prone to bounce with tragic in some cases accidental double clicks. Would say this is lighter and the tilt angle seems to be less. I would recommed as a good product at the price. Things I miss from the far more expensive Logitech model. The DPI settings steep up and down with two buttons on this trackball but the logi has a instant button to drop the DPI right down when you need to make a very precise movement. It would be good to be able to change the response of the wheel as it is great for Windows but far too slow for Macs which are tailored for the touchpad scrolling on the top surface of the mouse. Also what makes this less than perfect for me is that the tackball is shaped for smaller hands. If this is you then it could be the perfect device, for me though the wheel is about 1cm too far back for me to use, I have to change my grip to do so, not good for all day use.

This is a brilliant mouse. The ball has a nice smooth glide action coupled with accurate pointer movements. It is very comfortable to use and the tilt action makes it even more comfortable. I thought it was a bit of a gimmick when I read it in the advert, but having used it for a month or three now, the tilted angle is the most comfortable way to use the mouse. The connectivity is good and you can still use the mouse whilst charging. So there shouldn't be any down time.

I have to say, I love my Logitech MX Ergo. I have one at home and in the office. But when I saw this, and it was on Prime Day deal. I had to try it. ProtoArc have taken the MX Ergo and made some subtle but very good improvements. The Logitech is paired with my favourite K860 keyboard, but there's a slight design flaw. The keyboard can switch to 3 devices, the mouse only 2. The ProtoArc mouse not only solves this, it provides a nice way of doing so. Use option 1 with the 2.4MHz Wi-Fi dongle it comes with, or use option 2 or 3 with Bluetooth. This is awesome. Bluetooth switches so easily that it's pretty much an infinite selection, but with two favourites. Then there's a very simple but overlook feature on the Logitech. You have to take it off the magnetic plate to pop out the ball to clean it. ProtoArc made a simple change, put a hole in the plate aligned with the ball removal hole - genius. There is ONE thing I don't like. The roller has teeth, feels a little to rough on my baby smooth fingertips. But other than that, I can't fault it. For the £28 it cost me, a big saving over the £89 Logitech it's a great bit of kit.

I bought this to replace my Logi Mx Ergo as it was suffering from the dreaded left click fault.. I can honestly say this is a worthy replacement at less than half the cost. truly brilliant Trackball mouse, every ergonomic in fact it feels just like the Logi MX Erco it replaced .. 5 Stars all round and highly recommended

It was perfect, but in 3 months the ball is not smooth and keeps getting stuck. If I clean works ok for 30 mins and again gets stuck

I had high hopes for this trackball and when it arrived, I wasn't dissappointed. The packaging, as one comes to expect with ProtoArc products, was robust with a well made exterior box. Once opened, contained within the box was the usual product, in this case the trackball mouse, an envelope containing warranty and quick reference/installation guide along with a peel off contact sticker to stick on the underside of the mouse, and a further box which contained the 2.4Ghz USB receiver, a more complex manual and a USB lead for charging. As specified within the items description, the trackball has 7 buttons and a mouse wheel, which I presume also acts as a middle mouse button. There's the primary and secondary, back and forward, DPI plus and minus and the connection button which you click to switch between one of 3 connections; 2.4Ghz wireless, BT1 and BT2. Placing the mouse on a smotth table top, the mouse had a tendancy to slightly, very slightly slip such that every few minutes you needed to bring it back to where it started. This I'm sure would easily be solved by a cheap, rubber based mouse mat. The trackball moves smoothly and freely, perhaps a little too freely, but with the numerous DPI settings (5 if I recall, not 3 as it says in the description), more on this later, you can adjust the movement speed to your liking. Personally, I found a mid setting to be the most comfortable and manageable. The primary and secondary buttons are comfortable to click and you can actually "feel" them, rather than "hear" them with very little to no click sound. I'm not one for using back and forward buttons as I prefer the keyboard shortcuts so I can't really comment on them except to say that they also had this definitive "feel" rather than "hear" scenario, although a little less perfected than the primary and secondary buttons. The mouse wheel, which I never tested for "middle mouse button compatability" is nice to the touch although I found it to be a little too far down the mouse (too close to the palm) to be comfortable to use in relation to the primary and secondary buttons. This maybe due to my hand shape, I don't know, but I'm sure, once I'd been using it a while, I wouldn't notice it. Now those pesky little DPI buttons, and I do mean little. The position of them is probablly about right but, as they are so small, with my chubby hands I had a job to feel whether I was clicking the plus or minus one. Sure, there is a light which flashes a set number of times each time you changed DPI setting, but this light, which also acts as a charging indicator which goes out when fully charged, is under the thumb so, unless you move your thumb and/or head, you can't see which setting you're on until the mouse goes shooting off in an arbitrary direction. Now comes the main reason for me only giving this trackball 3 stars. For one, I'm not a pushover so, unless everything is perfect and I can't find any flaws with a product, you wouldn't get 5 stars and on this occasion it falls short of 4. "Don't keep us in suspense, what is the one thing that you're not happy with?" I hear you ask. Well, maybe not, but the thing I have to draw your attention to is the... and we'll be right back after these important messages from our... Whoops! That's for commercials. No, seriously, the one thing I have to draw your attention to, and the only thing I don't think I've covered, is the adjustable angle of the mouse. Firstly, when I read it I thought it was 0 to 20° but it's not. You can set it at 0° or 20° but nothing in between. Apart from this there is no locking mechanism to lock it in place. Rather it relies on, from what I can see look like magnets and, although there is a definite feel to when you change the angle, the angle was being changed much more than I liked. I may be a little heavy handed, but without this locking mechanism, I found I was having to move it to the angle I found most comfortable, which, if I'm honest was 0° so there was no need for this at all for me. Remember, this review is based on my own utilitzation of the **ProtoArc EM01 NL Wireless Bluetooth Trackball Mouse** and your own experiences might be different. Would I recommend the product? That's a difficult one to answer but I would probably say yes; unless you're heavy handed with short and stubby (but not that short and stubby) hands. In this case, I would say you'd have to try it for yourself and see how you get on. As the saying goes, "One man's onions is not necesarily the other man's bird in the bush".

I purchased this mouse to convert from a Logitech M570. I do love the extra features (rechargeable battery, multiple connections, angle adjustment & adjustable DPI). However, I have certain design issues with it, which may be due to my hand size (I'm over 185cm tall, for reference, if that helps): - Too little resistance on the main buttons. Completely relaxing my fingers is enough to accidentally right-click. - The back/forward buttons are too far back and too flat, making the back button awkward to reach. - The ball has a slightly scratchy feel to it (this one might be a bit more unfair, given the cheaper price to the M570, while having more features). I swapped the balls and it improved. I believe it will be a great mouse for people experiencing a ball mouse for the first time, or someone with average sized hands. After experiencing a more expensive mouse, there is just a bit of room for improvement, in my opinion.

これはとても良い！操作性も扱いやすいし、細かな作業にも気にならない。安価で検討してる方なら、これはお勧めしたい。

Such a game changer for working on my laptop at a small desk! I use this for my online assessments, Word, excel worksheets and it is nice not to have to move my hand all over the mouse pad. Easy with games that don't involve heavy combat and perfect for Baldur's Gate 3 and other turn based fighting. Two months and its still my favourite mouse.

TL;DR This is a premium mouse. It is great for CAD and graphic design, and also good for gaming and daily use. I know this is a bit intangible, but, it just feels like a quality mouse in your hand and has all the features you would expect from a premium trackball mouse. So I don't say something is a premium device lightly. Right from the start, before you even touch the mouse you know you're in for something special. There is pride put into even the packaging and presentation as you unbox it. First, I have some big hands, and it fits me well, and my wife has small hands and it works well for her too. the clickable area is about 2 inches long. it hits that sweet spot on size and button postion. The feel of it is great, I like that the angle of the trackball mouse can be changed from 0 to 20 degrees so I can set it to fit more naturally to my hand position when lying across a desk. This leads to less fatigue when using the mouse for extended periods with gameplay or CAD work. The mouse button clicks are nearly silent but with good tactile feedback, so this is great for office work, or at home where you don't want to disturb anyone. this mouse will not wake my wife :) I like that I can use this with multiple devices, using either the included dongle or Bluetooth. You can switch between devices quickly from the top. This is a big deal to me as one of my pet peeves with my other devices is that I ahve to turn it over to switch between devices. Changing the mouse sensitivity / DPI is also done just as easily from the top of the mouse. these two features are productivity multipliers. it says the charge lasts 300 days on Standby. I can't say yet how long a charge lasts in day-to-day use, but it sounds like it will last a long time. They don't say what standby means, does it mean off, or on but not used? I am not worried about it but I do wish the battery lifespan information was more relatable to usage time. Things I wish were better... Now do keep this in mind, I like the trackball mouse, but like anyone, there are always things you wish were different: for me, if it was jsut a little big heavier that would be nice. not that it moves around, i just like a bit more heft to the base. I would have liked it if there was a place to store the dongle on the mouse. it is always nice to ahve a spot for the USB dongle when you are not using it so it doesn't get separated/lost. I wish the angle was adjustable not just 0 and 20 degrees. I wish the mouse worked as a USB mouse also. I wish there was a left-handed version. Although the basic instructions are in all languages, I do think they should have detailed install instructions and images in all languages not just Chinese. None of these things are problems for me, but at least you know before you make a decision. Overall, I find this mouse to be very flexible, allowing me to easily change between 3 devices quickly and change the DPI on the fly. This is a great trackball mouse with features I find indispensable.

Nice stylish black trackball with (I choose) a red ball. Luckily no fancy LED lights, and connects to PC and MAC. Great!! What could be improved is a small storage area in the trackball for the dongle (wifi/bluetooth)
