I am a full time grad student, case manager, and intern. I bought it because I needed something silent and comfortable. The mouse was delivered February 26th and I fully charged it the day I got it. It is now April first and I am now charging it the second time. I use the mouse easily 8+ hours of the day and I am very impressed by the battery life. The mouse works great even when charging. The light up feature is cool but I rarely use it. I do not use it for gaming. There are a few things I don't like about it, listed below.

Pros:
Battery life!
Clicks are silent. Side buttons make some noise but it is not annoying. The primary left and right clicks are quiet, which is what I needed.
Works great when charging.
Lights are cool.
Speed and sensitivity is good for what I need it for.
Big enough to comfortably fit my hand
Makes a great cat pillow.

Cons:
Feels cheap. There is a large gap between the left/right click buttons and the rest of the mouse
On/Off buttons for both power and light is not completely flush. It caught and dragged on my mousepad. On my desk it worked fine. It was annoying. Ultimately I took a razor blade and shaved both buttons down. Problem solved.

So to preface this - I'm not using this on my main/gaming PC. This is sitting on a coffee table for my media center PC, so the use case isn't as intense.

The build feels a little cheap compared to something like the Razer DeathAdder, but it doesn't feel bad either. The clicking has a very light tactile response to it, but as I recall the soft sound was a selling point advertised. But there's still something off about the build - kind of like it might break if you dropped it from a short height, can't quite put my finger on it.

Battery Life - as I said, I don't use this all day, so I tend to get 1-2 weeks out of a single charge. After a few minutes of inactivity, the mouse kind of shuts off. Clicking/moving it will reactivate it.

Bugs/Issues -- There seems to be some sort of issue with the driver or the hardware after owning this now for 4-ish months where it's constantly picking up mouse wheel signals. I had to do a deep dive into this with a keylogger to figure out what was going on exactly, but uninstalling the driver stopped the issue, so it's definitely coming from this mouse. Not sure if there's something with the driver itself, or maybe with the mousewheel giving false positives? But either way, it makes modifying stuff like Google Sheets absolutely impossible.

Lights look great, have had no issues with burnout or anything like that. Get a nice little lightshow while they're on.

Loved it

Good overall mouse. Lacks the features of some higher-end models, but a solid choice for the price. A couple weeks in, I dropped it (obviously my fault), and it broke beyond repair. There is no material to help with grip, and it is fragile.

Great mouse for the price isn't a intense gamer mouse nor do I need it to be. Looks cool, feels well built, not dense or solid like I personally like, but still not cheap feeling. Battery life is only relevant with the lights on because why else would you get this mouse and to that I say it does well. You will find yourself charging your mouse 1-3 times a week depending on hours of use. Clicking is good enough, I enjoy it. All buttons work without feeling mushy. Pictures online are fairly accurate to the actual device you do get good light out of it and it does look very cool. For the record I got the White version of this.

Final Verdict: It is a mouse that looks cool and is still functionally acceptable. I recommend to the buyer that is here for the looks but doesn't want to compromise on the basics of what a mouse should be capable of doing.
