Nulea Wireless Trackball Mouse，Rechargeable Ergonomic Mouse, Easy Thumb Control, 5 Adjustable DPI, 3 Device Connection (Bluetooth or USB) for PC, Laptop, iPad, Mac, Windows, Android

Now I've gotten used to it, I like it. First "ball mouse" I've ever used in 30+ years so my muscle memory took some time to adjust.It comes with a wireless USB dongle (plugged into the base). Or you can use Bluetooth mode - there's a button on the bottom for switching modes. I've used both wireless USB and Bluetooth and they both work fine.I like the fact no mouse mat is needed. It works on my coffee table or on the sofa next to me.I wanted a top-ball mouse as my thumb is not as dextrous as my fingers.My right hand sits very comfortably on the mouse.The mouse has back+forward buttons which are handy in web browsers for going back a page and then forwards to the previous page. No need to move the mouse to the top left of the screen for the "<-" and "->" browser buttons.I charged it up on arrival. USB cable included for this. It's been running a week on a single charge, and I've been using it a lot. My previous mouse (single AA battery) would have died by now.The ball is removable for cleaning and has a decent weight to it. It'll hurt your foot if you drop the ball on it (I did this...).If you don't have space for an A4 mouse mat, or simply want to use a mouse on a sofa cushion without it sliding all over the place, then this is ideal.

This was my first trackball mouse after careful research. I've been using it for 18 months continuously on a near daily basis and am very pleased. The only issue I've had is the rubber tread on the scroll wheel started to slip after about 6 months use, but was nothing a drop of super glue couldn't solve.The mouse is comfortable under the hand but takes some getting used to if you've never had a track ball before. My preference is to have the track ball under my fingers rather than at my thumb, and I have gotten very good at flicking the mouse cursor across my three 27" screens.I've had to recharge the batteries a total of 4 times in 18 months, which I think is excellent.I would maybe class it a touch on the pricey side (I'd love to have a second for another PC), but can't quite justify the cost for something that will only get used occasionally). As a one off purchase though it's worth it.

I have been very pleased with this trackball. It works efficiently and has a larger ball than most which gives greater control. Not having a wireless mouse/trackball before I have to remember to wake it up before using it.I really like it

An excellent device that, for right hander at least fits perfectly in the hand, support eith with the included dongle or by Bluetooth. All the buttons are well positioned and give a satisfying click. Would recommend to anyone who has joint issues or just can't get on with mice. Just plug in the dongle to a free USB port or connect via Bluetooth and go. Supports all your regular OS's without issue as well as Linux. A touch pricey perhaps, and delivery speed was glacial. But I think worth it in the end.

This is an excellent trackball, I know it will take a little time to get fully used to it, but I found it to be best one I have ever used so far.It fits your hand ever so well.The Bluetooth connect is great.The fact that the buttons are not programmable is actually a good idea, it means the trackball mouse does exactly what it was designed to do brilliantly with no messing about with other software interface etc.Keep up the great work Nulea.I am going to keep an eye on Nulea, as I understand they are a relatively new startup, and if this product is anything to go by, I can only expect great things to come from them.

After a few hours of getting used to it, its greate. Make sure to adjust the dpi and cursor speed in the windows settings, so you can get it just right. I'm never moving my hand again, only my fingers.It funny you have to basically re-learn how to press the LMB, because its on the thumb now, but it's not the end of the world.I bought this because I wanted to try it for the first time and I admire the ergonomics of not having to move your whole arm to move the cursor, and I dont regret it.The quality is the average $30+ mouse out there, not cheap plastic. Its bigger than most mice, but its nice to use on the palm.

Love this product. Really easy to operate

Great trackball, I was worried that it would be uncomfortable to use, or really really big, but its a good size and fits in the hand well. The ball has a nice bit of weight so you can spin it and it'll freewheel from one side of the screen to the other and is very controllable.I've been having fun with it, no issues so far. Charge lasted me a week or maybe more, so no need to constantly recharge which was a worry.Scroll wheel is a little less notchy than I'd like. I also noticed a couple of missed scrolls, where the wheel would move a notch but the screen wouldn't scroll. This happened both in-game and on webpages. Not a big deal for me

Just received it and unboxed and tried it out. First impression is that the design is exactly what I am looking for and how it feels while being used. The texture is pleasing (although I have doubts that this matt texture can survive more than a year’s use of daily 5 hour use) and the positions of the trackball and buttons are placed where I want them. Both left and right click buttons click downwards and not inwards which is a positive thing for me. The DPI switch which easily allows me to determine the speed of the arrow travel each time I touch the ball is a godsend compared to other trackballs.This trackball has a rechargeable internal battery - which I hope will last a long time. Always found that rechargeable devices often die due to the battery.It comes with a 2.4Ghz dongle or useable with Bluetooth connection. I have not tried using the rechargeable cable as a direct wired connection to the computer yet but I do not think a wired mode is an option. Will update on this later.Overall on initial impressions and use, this trackball is better than I had hoped and as a trackball user (Microsoft, Logitech, Elecom, etc.) this has so much promise. I will update again in a few months. If my impression is sustained through use in the months ahead, I plan to buy a few for my family and myself at home and office.

Exellent trackball aussi bien que logitech

Ottimo. Sono anni che uso trackball ma qursto è veramente comodo e preciso

Excelente producto

Aunque no me di muy bien con él por estar acostumbrado a usar ratones verticales, es un trackball muy bueno.Pros:- Es muy cómodo de usar- La posición de los botones es muy cómoda, todo un acierto, sobretodo los botones principales- Resulta muy preciso su uso- Acabados muy buenosContras:- Por el precio no le encuentro ninguno, se agradecería una rueda de scroll infinita, pero sería ya mucho pedir
