Just posting in here to give people a heads up. I've been using razer for the last 10 years, but when replacing my mouse (razer viper 8k Hz and only 2 years old) it would not work on my mouse pad (my old viper did). Went through all the trouble shooting steps and nothing worked software side. Tried different surfaces. Other computers, even my android. All the mice were broken. Completely ridiculous.
Returned the mouse and got a new one. Again, broken out of the box. Returned that one, maybe third time is the charm, nope. Decided to get a Logitech g403. Works perfect out of the box. And half the price for essentially the same mouse.
Again, my razer keyboard is shutting the bed after a year and a half. Their quality control seems to have gone extremly downhill.
Don't buy razer.
