You can print your invoice/proof of purchase from your Amazon order history, so you may yet be able to send it back or get warranty service.

can't say if your issue is exactly the same as the one i had but my razer diamondback kept cutting out just like how you said, i fixed it by taking it apart and replacing the cable with one from an old dell optical mouse i had knocking around. inside the mouse is a small plastic plug with 5 wires attatched i had to rearrange the wires going into the plug by removing the spades and swapping them around so they matched the original plug.

i found the best way to remove the spades is to get a fine pin or needle and lift the little bit of plastic holding them in, if you do this right they will slide out effortlessly, make sure when you rearange the wires that they're put in the same way as the cable you are replacing else it may not work properly.

put the mouse back together and plug in and it should be fine, it took me 10 mins to do this to my diamondback and its working like new again.

search it on bing.

This is going to sound really stupid, but if I was just having the exact same problem as you. I launched the Razer Synapse 2.0 program and save that my up key had a macro that did nothing. Once I changed that back to the default single up key function, it seems to be working fine.
