When Gravastar first reached out and asked if we wanted to take a look at their new gaming mouse, I was a little apprehensive. Gravastar are usually known for their funky spider-like Bluetooth speakers, like something out of Half Life, not gaming peripherals. But still, I went in with an open mind. When it arrived though and I got it out the box for the first time, I was a little shocked about what I found. Yes gaming mice with holes in their bodies are nothing new, brands have been doing it for a while now to keep the weight down. But this? This is something else! Usually, gaming mice have small holes, similar to that of a honeycomb, but here, the Gravastar Mercury M2 is basically a plastic skeleton, and to be honest, it works, and after using it now for the past two weeks, it works well and I’m really used to its unique design now.
So why all the holes? Well, apart from Gravastar wanting a unique-looking mouse, it’s actually for a practical reason, and that’s to keep the weight down. The net weight of the mouse according to Gravastar themselves sits at 79 grams, which isn’t anywhere near the lightest mice on the market, especially when you’ve got the Model O from Glorious coming in at around 67 grams, but it’s still considered light. Well, compared to my Logitech 502 X Lightspeed anyway which weighs 102 grams. But Gravastar I don’t think was going for weight loss more than they were going for design. And although super strange, in person it actually looks pretty cool. I like it and hats off to Gravastar for trying something so bold. The size of the mouse though for me personally makes it hard to adopt a proper palm grip. It’s a bit too skinny for that. But I can very comfortably use this mouse in a claw grip without resting my hand on the mouse itself. A far cry from what I’m used to with my 502 X, but still, a comfortable experience, despite what you might think from the design.
Apart from the crazy design, the Gravastar M2 is pretty much a standard gaming mouse from here on out. It’s got top left and right clicks, a scroll wheel that rotates in increments and has a rubberised indented texture. Two thumb buttons curve around the left-hand side where your thumb would naturally land anyway and inside is an RGB bulb that can be set to various patterns and effects inside of the Gravastar software.
On the bottom, you can find Teflon pads which aid with the glide across a mouse mat, and just to throw it out there, Gravastar are also selling mouse mats too. A link will be in the description. As well as pads, you’ve got a sensitive PAW3395 chip which is capable of hitting a 1,000 Hz polling rate and up to 26,000 DPI though that is crazy if you’re ever playing that high. I’ve set my mouse up to hit in increments between 400 and 1,600 DPI thanks to the driver, and this can be cycled via the button underneath the scroll wheel, and it’s also colour coordinated too. Being a 3395 sensor, you’re also treated to MotionSync, which has been designed to synchronise the sensor readings with polling events, making the motion more consistent. This can be turned on inside of the driver, along with ripple control and angle snapping, though I dd keep these off. Angle snapping for sure because it interrupts games way too much, and ripple control which is a movement correction to make mouse movement feel smoother. Maybe on a desktop this can help, but in games no way. The M2 gaming mouse worked well when I was playing some competitive Overwatch, and movement feels really nice and smooth with my mouse pad which admittedly is a budged pad from Amazon, and the clicks were nice and tactile and accurate.
Inside the driver, there’s not a huge amount else than what we’ve covered already. You’ve got the option to set up your own macros if you want, and customise your LED lights from a rainbow pattern or for it to cycle colours. Every time you open the software it checks for automatic updates which is nice. You can change key assignment too if you want your left click to be something else for example. And you can save all of the settings into presets for hot switching for different games of software. It’s really nice to be able to customise the M2 so much to really suit your gameplay style.
So that’s the Mercury M2, and it’s a fantastic little mouse that okay, hands up, looks absolutely bonkers, but actually performs really well, thanks to that customisation options in the software. The Mercury M2 comes in what they’re calling Stealth Black which looks rather switch, and has some proper funky branding on top. You do get stickers in the box though if you wanted to cover this up. I haven’t because I quite like how it comes, but you’ve got the choice. It’ll set you back $79.95 which isn’t bad, but certainly isn’t the cheapest, especially for Gravastar’s first time out. But still, it’s a nice mouse, I can’t take that away from them. They’ve done a great job with this one.
