Hardware-wise this is a pretty good mouse. Resolution is nice and it's very responsive (at least over 2.4GHz - haven't tested Bluetooth). Definitely beats my old wired mouse. I've had it for about a month and use it roughly 12h/day, 5 days/week (work + gaming) and I'm still on the original battery
Big problem #1 - Laggy input in some cases
I have a fairly regular problem where the input gets incredibly laggy (unsuable for desktop applications laggy) if my screen resolution changes. This happens when I turn on my TV to use as an external monitor, or when I install a new game and it runs at the default resultion. The only fix is to reboot my PC. If it happened once it would be annoying but acceptable, but this happens several times a week
Bigger problem #2 - privacy
If you want to configure the mouse in any way (or view the battery level, etc, etc) you have to install Razer Synapse. There's no way to run Synapse without registering for a Razer account. So now you've got an application monitoring everything you do on your computer ("information about your activities while using our hardware or software or while logged into your Razer ID account") and sending it back to Razer. Their privacy policy allows them to connect this to your identity and send it to any country that has lower privacy standards ("a destination outside the European Economic Area (EEA) in which data protection laws may be of a lower standard than in the EEA").
Remember you've paid full price for this product, yet you still have to agree to have all of your activities logged and sold by Razer
For the above reasons, I would avoid this product, and unfortunately any Razer product, until the issues are addressed
