Mercury M2 Gaming Mouse -MMO Computer Gaming Mice with 26,000 DPI Optical Sensor -78g Lightweight Hollowed-Out Design -5 Programmable Buttons -5 Dynamic Lightsync RGB Modes -Stealth Black

I had my eyes on this for a while and was skeptical. It truly blew me away after a few hours gaming. Feels and looks INCREDIBLE. Nice and light, and always my heads sweat less using this due to all of the design.The battery life has also been amazing thus far. Outstanding mouse and it’s the best I’ve had to be honest. I’d definitely suggest copping this.

This mouse performs great, it looks very cool and unique. But I think comfort maybe a problem for some person, depending on their style of grip. Sadly for me, it was just the little bit too different and uncomfortable for me, so I had to return it.However, if the mouse is comfortable for you, then it’s definitely one of the best performing mice I have used.

I’ll talk first about the design as it is really eye catching and really helps the mouse to stand out compared to other gaming mice I own. The hollowed out, wire frame design is aesthetically pleasing, but it also works well at ensuring my hands don’t get too sweaty during more intense or longer gaming sessions. It also helps to keep the mouse nice and lightweight.Inside the palm section of the mouse there is a transparent plastic housing, which is used for covering the GLOWSYNC RGB lighting system. These lights add some excellent atmosphere to the mouse and offer five pre-set dynamic lighting options or you can set your own with software you can download from the GravaStar website.As well as selecting your light settings the GravaStar software also allows you to fine-tune the DPI settings, adjust the button commands, set macros and establish multiple configs, perfect for tweaking your mouse for both work and play.The mouse can be connected to your devices three different way, either Wi-Fi, Bluetooth or via the supplied USB to USB-C cable. I prefer to run my mice connected to my computer via the cable as it reduces the chance of lag and interference, so you can have optimal gaming performance. Connecting via Wi-Fi is provided via the supplied dongle which you install into the bottom of the mouse if you wish to use this method. Bluetooth connections work as standard. The manual explains how to connect you mouse with whichever method you choose.Also included with the mouse are a microfibre cleaning cloth and a replacement foot pads and a selection of anti-slip stickers. The anti-slip stickers can be attached to your mouse as you see fit and can improve performance for longer, more intense gaming sessions, by offering better traction for your fingers.The buttons are quick and responsive, and the mouse control is smooth and comfortable. The pre-set DPI settings are helpful, but you can configure your own, and you can set the maximum DPI to 26000, which will allow you to fine-tune the mouses responsiveness to better suit your different gaming needs.I am super happy with this mouse and would happily recommend it for its stylish and appealing design, comfortable grip and excellent performance.

I originally got this mouse for myself. I'm not a game, but I do like a decent ergonomic mouse with fast speeds and as I work on computers all day, I thought this would be great for me. But I just didn't like it - it felt too slippy and the holes in the design made me feel like I was using a broken mouse - it's much too lightweight for me to be comfortable with.I donated it to my son to try - he's the gamer in the family and he has done nothing but rave about it - he thinks it's fantastic and the best mouse he's ever used. He said the 26000 DPI makes all the difference, his hand doesn't sweat even after hours of playing, the responsiveness is fantastic, and the lights just make it look cooler than it already is.You can connect to an app to customise the buttons and lights but he's happy with the set-up as it is and said it feels superb to use - in other words, he doesn't want to download another app to his phone as that would take some effort.I was going to give it 3 stars but he said it needs 5 so I compromised on 4...

I have to say, this mouse has a very unique design and feel to it, almost organic but pretty alien overall, and it won't be for everyone—but I think it looks incredibly cool! I've been enjoying using it, finding the experience fun in a sensory way. The mouse is basically very 'ribbed' on account of the skeleton approach to the casing. The buttons themselves are smooth, but the rest of the mouse, as well as the scroll wheel, feel very textured.The mouse weighs around 81g, which makes it fairly lightweight. It has a symmetrical shape but back/forward buttons only on the left side, so it’s very likely a mouse for right-handed people.By default, the light turns off when you move the mouse, turns on after 1.5-2s, and then times out and turns off again if you leave it still. This means the light will sort of come on and off periodically if you’ve got the mouse in hand and doing low-frequency office things with the mouse. That may or may not be annoying. Based on what it says in the user guide, the lighting setup is configurable, so presumably you’ll be able to turn this feature off if you find it frustrating.There is easy pairing via Bluetooth—on the bottom of the mouse there’s a toggle between 2.4G, OFF, BT.The DPI adjustment works well; when you press the DPI switch button, the mouse will light up in a color specific to that setting, which means you can use colors to identify which DPI setting you’re on.Tracking feels smooth. My usual test for this, and how I realised my old old mouse was bad, was that I can move around a window on my 144Hz monitor and it moves perfectly smoothly and without any hiccups. I’m not a pro gamer by any means, but it feels nice. The mouse tracks well on my desk, and on a mousepad, and generally matte surfaces. It doesn’t track at all on the screen of my iPad, which is hardly a common scenario, of course, unless you have a glass table; but I have used other mice which allow this, so this does mean the sensor on the Gravastar has some limitations.There is no freewheeling mode on the scroll wheel, and you've only got two extra buttons. That's not a deal breaker; it’s definitely a decent mouse which feels great in use. So, while I imagine some gamers would say it’s not enough (there are gaming mice out there with macro buttons, entire pads of buttons, etc.), it ultimately depends on the individual.
