-Light weight and good battery life (it lasts me over week). Keep in mind I keep the lights off and turn off the mouse if I don't use it. -Ambidextrous shape, so I can use with both hands comfortably. -Included cable to charge / plug wireless receiver is very nice. I feel like it's also a premium wired mouse if you need to use and charge!

-The software side is very poor and frustrating. Glorious has it's own Glorious Core just for the wireless model which is not the same for the wired Model O! Updating automatically to the latest version doesn't always seem to work, and getting firmware for the mouse through the software itself can be frustrating. It's not a polished experience and definitively a weak point. -Out of the box, this mouse had angle snapping issues. I tested this by drawing circles that resulted in a more square shaped circles. This issues seems to have been addressed with a later firmware and seems to be as good as my previous Logitech G400s mouse in drawing. If this is important to you, try to download the latest update. Some would argue that this mouse is not a perfectly 'flawless' sensor, but for me personally I could not notice the difference afterwards.

Great light wireless mouse. I haven't had any of the quality control issues, I guess I am a bit lucky in that regard? Have been using daily for 3 months now and haven't had any miss clicking, sticky buttons or other weirdness. It's as good as the day I got it. The build quality in my opinion is great, it feels like a solid plastic shell and the buttons are crisp. The honey-comb holes don't bother me, I didn't find that I get the mouse dirty or anything. It's also easy to blow some compressed air if you want to clean it out I guess.

-wireless with great connection -customizable -light

Quality control is badd, bought this mouse and with in 2-3 weeks the macros stopped responding to the side buttons the program to control all of this was horrible user experience too, the none wireless model o (my current mouse now) had a great software so I bought the wireless one thinking the same thing but my right click button was squeaking and the side buttons stopped responding to macros in the software, the charging cable seemed to only go in one day and with lights on I could only get around 1 days use out of the mouse which was usable but annoying if you forgot to plug it in!

If you get a good batch you will still have to deal with charging it and dealing with the bad software but the software would be updated and would be worth if you got a good quality mouse if it stops working like mine did then it’s not worth it, kinda random but it’s worth those downsides(like software and charging) for wireless if it works and doesn’t stop responding to macros and such as I listed above, overall I’ll still be using this mouse and I’ll return and rma until I get one I was promised while purchasing it!

Nice shape, cool RGB, great sensor, and it's much lighter than the other wireless lightweight mice that I own.

Very poor quality control. Battery doesn't seem to last that long even with the RGB turned way down. Mushy clicks on my model.

I had this mouse for about two weeks, no issues. Then, today, out of nowhere, the right mouse button just started squeaking very loudly and would stick. This is the second Model O (I also owned the wired version) that I have had major issues with. I purchased the the warranty for this mouse, but I honestly don't even want to bother with it. I wouldn't even feel right selling this to another person. I'm done with Glorious products at this point.

Took about a week to receive it. So far everything work well. No weird sound, no rattling. I totallly love it.

The mouse was good for a few weeks before the wheel started squeaking horribly. Now the scroll wheel randomly started to scroll up for no reason. Lubed the wheel as Glorious support suggested but it didn't help the problem at all. There seems to be some quality issues with this model.

After watching reviews on this mouse, I decided to purchase this mouse. Was a great mouse until the RMB started to squeak/felt sticky/ not being responsive. Most disappointing part was I just recently brought it and only game a few hours on it.
