My favorite gaming mouse I've ever owned

I've used quite a few gaming mice over the years, and this is easily my favorite. I'm a huge GravaStar fan, and this mouse absolutely lives up to the hype. I mainly play Apex Legends, Call of Duty, and Fortnite, and the accuracy and responsiveness are insane. It feels incredibly precise, making quick movements and tracking feel effortless. One of my favorite features is how customizable everything is. After downloading the software, you can adjust the polling rate, DPI, RGB lighting, button functions, and even the breathing effects for the lighting. It's easy to use and gives you complete control over how you want the mouse to perform and look. The lightweight design is also extremely comfortable during long gaming sessions without sacrificing durability. For me, this mouse has been worth every penny. If you're looking for a premium gaming mouse with excellent performance and endless customization, I highly recommend giving this one a try. This is a mouse that will last you forever and thats why I bought it. ... show more

Very Cool, but does have a premium price for the extra coolness

It has been a long time in the accessory space since a company came out with products that were different and unique but didn't also stink at the function that they are supposed to perform. This is not one of them. Like their keyboards, GravaStar has made this crazy looking mouse that is actually an excellent gaming mouse. (Or just mouse in general.) It is a premium product at a premium price so I do have a few nitpicks, but overall it is an excellent mouse. Taking it out of the box, and it is both very light but also feels premium. Squeezing it much harder then I should and it is very rigid and strong. The web based configuration is okay. Since I have one of their keyboards and the software that comes with that I think it would be nice if that was integrated into one system. Otherwise it is nice to be able to fine tune the sensitivity and even though I had no issue with debounce (clicking once and sometimes getting double clicks) but it is nice to be able to adjust that. And finally something that I never thought I would say... I like the RGB. In generally it just seems sort of silly to have RGB on a mouse, but this one makes it work and adds to the whole vibe, especially when paired with one of their keyboards. Actually gaming with the mouse is great. Despite the crazy look it is very comfortable in the hand. The main left and rright buttons have just the right amount of click. The side buttons are well placed (something that a lot of mice seem to struggle with). My only minor quip is with the scroll wheel. It is okay. It is a little soft and squishy feeling and the click takes a bit more force then I think it should. Given the rest of the mouse's construction it does stand out to me. Again, it is still my favorite mouse but when it costs a premium price then the expectations are also high. After playing a bit and getting into the game though, I stopped thinking about the scroll wheel though. In conclusion comparing this to another gaming mouse that costs about 1/3 as much, the cool is a big part of the price. For me the GravaStar is more comfortable and a lot lighter. The clicks are a bit better. With the DPIs set the same though I really could not tell the difference between the mouse with half the DPI and polling rate. For me though, the cool factor still makes it worth it. ... show more

Great fancy mouse
Color: Black Style: 8K Polling Rate
Really nice mouse. I love the look of it. Love how Alien type looks, my hand is really small and have palm rest on it and i love all of it!. I was scared at first that would be too big, but nope fits perfectly for small hands, it feel sturdy and very light. So far it have lasted great I will update if something happens, the battery life is great i'm someone that love have the lights on all the time and always forgets to charge their mouse. I could be more than 3 days with 8+ hours play time and it last for long. ... show more

Superior to premium plastic mice
Color: Black Style: 8K Polling Rate
Perfect design and great build quality. I wear Large size gloves and I prefer larger than normal mice. While the Mercury X is not as big as my IntelliMouse Pro; I still prefer using the Mercury X. The biggest reason is that I like the stiffness or rigidity; I feel like this helps keep my hands from getting tired after working/playing for a long time. Also, the material does feel cooler to the touch. All plastic mice get sticky after an hour of play since our hands release natural oils. This Magnesium Allow does help with this; though, I'm not sure how much I would attribute to this factor or the skeletal design itself. The slotted/skeletal design does not negatively affect your grip as I've read on the forums that some people are worried about. Instead, because the sides are slotted, you don't have that sticky/oily thumb feeling that you get with even a high-end plastic mouse. I like this enough that I purchased both the Mercury X and the Mercury X Pro. Both are identical aside from the fact that the Pro allows for 8k (which I don't even use) but it was on sale so it made the upgrade the same price. Oh, connection via dongle is the only way I do it and it works perfectly. The application to manage and update the mouse is simple to use and does not install malware. Value: Absolutely worth it in my book. Its like a monitor, you're staring at it all day so ante up and buy a good quality one. Do the same for the keyboard and mouse that your touching all day. ... show more

Insanely Good Gaming Mouse; Fast, Lightweight, and Beautiful
Color: Black Style: 8K Polling Rate
The GravaStar Mercury X Pro completely blew me away. This thing is a BEAST for gaming. The 32,000 DPI PAW 3950 sensor is incredibly precise, and the 8K dongle with the 8,000Hz polling rate makes every movement feel instant. No lag, no stutter—just pure responsiveness. At only 49g, it’s unbelievably light but still feels solid thanks to the magnesium alloy hollow frame. It’s comfortable during long gaming sessions, and the build quality feels premium, not flimsy. The RGB lighting is the perfect touch—bright, clean, and customizable without being overdone. The 5 programmable buttons are super handy, and the software makes it easy to set everything up exactly how you want. Whether you're playing competitive shooters or just want a high-end mouse for everyday use, this one delivers. Absolutely worth every penny. This is easily one of the best gaming mice I’ve ever used! ... show more

From a mouse junkie... Nearly Perfect
Color: Black Style: 8K Polling Rate
I was pleasantly surprised by the Gravastar Mercury X Pro... This mouse is really great and has the features we're all looking for (3950 sensor, 8k polling rate, adjustable LOD, motion sync) all wrapped up in a downloadable OR web interface. I love having the choice - you can configure the mouse via webpage, or via the software to download. The RGB is great. I usually don't pick mice with it, I go for the $100-150 class mouse (I have around 10 of them, too). This mouse is definitely up there in the quality department, it feels just as nice as my other $170 magnesium mouse. The look is stunning and unique, I love the default colorway and it really stands out. It's a pleasure to use, except... Side slits :( Side slits :( Side slits :(... this is the only thing preventing me from giving it 5 stars. Your thumb and ring/pinkie fingers on the side of the mouse will be holding slits. It's not so bad, they feel okay, but man would this mouse feel amazing with solid sides. I'm recommending to the vendor: Make the sides solid in the next revision. Give us something nice to hold onto. Ultimately there are two types of customer feelings about side slits: you've got the people who don't notice or care, and you've got the people that the side slits drive nuts. I am one of the people who go nuts about them. Your design is either going to drive people nuts with the feel of side slits, or it's going to be ignored by people who don't even notice. If you go with solid sides, you'll please people like me, and the rest of the customer base won't even notice. All in all I would give this mouse a square 8/10. It's almost perfection, every single spec ticks the right box for a high end mouse (what type of switches were used I don't believe was listed - they feel pretty good generally, I can't tell if it's optical or magnetic so I mean, good job). Maybe improve the switches and give us solid sides for the next version, and that'll be an 11/10 mouse. ... show more

Sick high quality
Color: Black Style: 8K Polling Rate
Excellent item, I’m coming from a Logitech g502 pro wireless that is a pretty heavy one, I use it for play fps games and I have to say it works perfectly. I play full hand so I was worried about the size before get this one but I have to say that for the minimum weight, it has a pretty decent size that feels great in the hand. You can feel the high quality there and the software is pretty easy to use. And also looks sick. Great value if you constantly play and want something of quality ... show more
