A quality mouse for everyday users
Size: Standard
I was tired of using a mouse with cheap switches. The only choice was to upgrade to a Gaming Mouse with switches made to last. I don't do much gaming except solitaire. The mouse is comfortable to grip. The buttons are easily reached. The size is much better than a compact mouse. The surfaces that you touch have a light grain, not slick like others. It is easy to adjust the mouse speed and know the computer will respond when you press the buttons. The thumb rest is a nice design and adds a little to its footprint to make it glide even easier. The battery cover is magnetic and easy access to the one battery. I needed Bluetooth to not have a wireless dongle stuck in my laptop. It ruined one from hitting my leg. A well made mouse even if you are not a gamer.

Works good, looks nice. Chews through batteries
Size: Standard
I'm not a huge gamer, but in general it's a pretty nice mouse. The mouse movement is rather fluid and it glides smoothly on my mouse pad. Don't have any issues with connectivity, but I do have the dongle very near the mouse. You can customize how the colors rotate with the Razer program on your desktop. There are several buttons you can customize as well and change how long before it goes to rest mode. I also like that I can accidently bump it and it won't wake my pc from sleep mode (though sometimes I do have to jiggle it around a bit for it to wake my pc up). I love the shape of it alot and the thumb rest, very comfortable in my hand.
My only complaint is that I am chewing through batteries like crazy. I feel like I have to replace them about once a month. Will probably invest in rechargeable batteries. But this is a great option for anyone who is looking for a better quality gaming mouse without spending $100+

Smaller, ergonomic, lightweight, VERY quiet and soft click
Color: Grey
I'm about a month into using this mouse, and so far it checks every box besides being rechargeable. in other words, I preferred battery operated ones as I have no way to use this while its plugged in unless I reroute my whole PC setup just to be able to have access to a USB C cable. I purchased a second mouse for backup. Anyway, its a great mouse, thats extremely lightweight and responsive. the button click is EXTREMELY light, which I love, (similar to a new model macbook pro touchpad click, possibly even lighter) and the overall feel is ergonomic/small which i prefer, since I like to be able to move the mouse around with my fingers rather than my wrist. I use it for my main home PC while using my DAW for music production. The DPI feature is cool I suppose, but I don't really need a quick-access setting to change mouse responsiveness on the fly. My only gripes are two; that I wish the side thumb buttons were moved back toward the wrist a bit more. I can only effectively reach the rear button with my thumb, but the forward button requires me to shift my hand around the mouse each time to click it. Its actually easier to slide my index finger off to the side and press that button if I need to which is weird. My second gripe is the charging: I used it for the whole month (8+hours a day work) and I needed to charge it by the end of the month. Which is not bad, but nowhere near the 6+ months of battery life using a single AA. It does not have an energy saving feature similar to mice I've used in the past (click to wake up), also the little battery indicator doesn't make sense. It only goes off when theres no connection to a PC i.e the PC is turned off. It did not indicate when the battery was low, charged, or charging. I plugged the mouse in when it finally died (which was unforgiving, its not like it died, and I could pop the battery in then out to pause a game, or stop music playing, etc.) and it was underneath the clickers that illuminated red (im assuming that was charging, since instructions weren't clear) and then it was green at some point. Simple enough to figure out, but strange that the battery indicator itself didn't function that way it was supposed to. Charging was fairly quick ~an hour or so? We'll see how it fairs in the long run.
Overall, Im happy with this mouse in the short term

Super Nice Mouse for the Price
Color: Grey
I've been using this mouse as my primary mouse for 3 months now. I bought it as a backup for a more expensive mouse that was showing its age but I like this one SO well, I've kept using it. In my opinion, it has a nice feel and works very well. It's lightweight, glides smoothly, is responsive and quiet, and the battery lasts at least a month with several hours a day of use. Connectivity has been seamless. I did download some third-party software to increase the functionality of the side button. Just be aware that if you like a larger, heavier mouse, this one may feel cheap to you. But I really like it a lot.

Marvelous, Versatile Mouse
Color: Grey
I was torn between getting a wireless or a Bluetooth mouse, but this product eliminated the dilemma altogether.
It paired painlessly with my MacBook and synced seamlessly with the wireless dongle plugged into my Windows machine. No noticeable lag, but I did not test with games.
The mouse feels comfortable in my hand and has just the right amount of heft so that it doesn't feel like a cheap dollar store mouse. The feel of it rivals my more expensive Logitech mouses. Buttons are extremely quiet and provide satisfying tactile feedback.
But I think the clincher is all the thoughtful details. I love that I can stash the dongle inside the mouse via a slot on the bottom. The switch to toggle between Bluetooth and wireless, or to shut off the mouse in order to preserve power, is a nice touch. And the recharge capability is as advertised. So far I've been using the mouse for two weeks straight and don't foresee it dying anytime soon. And if it does, it's nice to know I don't need to worry about batteries.
Overall, this is the perfect portable mouse to stash in my laptop bag and break out in just about any situation.
