GravaStarMercury X Pro Wireless Gaming Mouse, Come with 8K Dongle – 32,000 DPI PAW 3950 Sensor, 8,000Hz Polling Rate, Only 49g, Magnesium Alloy Hollow Frame, RGB Lighting, 5 Programmable Buttons

Ridiculously light and unbelievably responsive with a HUGE range of adjustments and the App is simple and easy to use. I play very fast paced, demanding games on a high end purpose built custom gaming PC and so far this is the best mouse I’ve used. Zero lag and very smooth movement I highly recommend.Just a side note: it is extremely light and may have you questioning the material but it is definitely magnesium allow. It’s very thin but very solid material and cold to the touch it’s awesome and it comes with 2 styles of grip tape

The most amazing mouse I have ever used and owned! Most precise mouse available.

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.

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.

Left it plugged into the computer to charge for work while the computer was off battery melted this has never happened to me on any of my mouses before.

Very fast and extremely light weight. Would highly recommend adding the cool textured grip stick on pieces that come with the mouse.

I ABSOLUTLEY LOVE LOVE LOVE the feel of this mouse. It’s so comfortable, responsive and dependable. It looks amazing!
