They seem to have a lot of these refurbished mice, wasnt sure if it was dodgy or not.

Well I guess for £11.99 its worth a shot.

not if the buttons fail and you have no warranty.

I bought one, it seems okay except there's a slight jitter issue when moving very slowly. Might be an actual problem with the sensor/lens rather than it being second hand. I don't want to take it apart without having backup skates just in case they don't go back on properly, so I'm not sure what to do.

EDIT: Fixed by changing mousepad. Doesn't work with Razer Goliathus Fragged versions, with the big green pattern, causes jittering. Using a Zowie G-TF and it works amazing. Sick mouse.

a new one costs ~16$ in Russia so it's possible to find a new one for this price
