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.

Genial mouse , just need a better app... Buts works perfect

So far the best mouse I have had it's got a sleek cool design it doesn't feel like any resistance or drag it's very lightweight so far great for gaming. The dongle isn't bad only issue I have is the software that comes from Gravastar is thru a Google document/library and gets flagged by most security systems or security apps and picks it up as possible malware. Have not had any issues or seen any issues from using it or the software. Has some serious DPI to it and like 6 LVLs of adjustment with a button on the bottom of the mouse you can press easily.

Excelente producto les dejo mis 5 estrella muy bueno rápido excelente diseño estoy super conforme

Super light! Looks cooler than the photos.

Please feel free to ignore if you like your mouse to be super light.I don't know what gamers are into these day, but at nearly 40 years old I thought a quality mouse should feel more solid than this and have a satisfying click. This might be made out of cool stuff, but if I closed my eyes I wouldn't be able to distinguish this mouse from a bargain bin wireless mouse. I wish it was heavier with a stronger click.Oh well, it was a gift for my wife's gaming setup and she seems to like it just fine, so its probably just a preference issue.

false advertising. this thing is CHEAP plastic. i have to M2 and it is LITERALLY magnesium. This "X" is cheap garbage.

This mouse is part sculpture part high tech mouse. The exoskeleton looking exterior is a marvel to behold. The mouse is so light it's hard to believe it's made of metal, the wonders of magnesium. Great looks aside, it fits and feels quite good in my XL size hand. Button clicks are positive with a good tactile feel. The scroll wheel has a good amount of resistance with positive detents in-between.The performance with the included dongle it top notch. 8K polling rate with the software I tested it with. Not sure how real world useful having 8K polling is but it's nice to have. I noticed a bit smoother operation between 1K and 4K, but 8K I didn't see much difference. Your milage may very. Overall sensor performance it top notch. With multiple games I tested with this mouse tracking was superb. Lift off felt good and no tracking issues whatsoever.The RGB looks great inside the magnesium frame. It looks like a beating heart of some alien creature. This mouse coupled with the matching GravaStar Mercury K1 Pro keyboard on my desk look absolutely amazing.The only drawback, if you want to call it that, is that the right and left mouse buttons are plastic. Sine 99% of all mice buttons are plastic, this doesn't bother me in the slightest. I am very partial to using skins on my mice, like what is included with this one. I love the feel of the slight padding the grip tape offers and it makes the mouse clicks change tone to a lower sounding click. If plastic buttons bother you, be warned.Overall I have been thrilled with this mouse as it is my new FPS mouse of choice. The only thing I would change if given the option would be to add right and left scroll clicking to the mouse wheel. That small thing aside, to me, this mouse is perfect.
