I've got one of these and its pretty decent. It does on rare occasion suffer from the typical Razer peripheral drop out. Where the mouse wont come back to life until its reconnected. What I like best about this mouse, is the two buttons of the left clicker. They are in a great position for gaming.
Yes, its been cheaper and may be again. $65 seems a fair price.
Negative is that it uses AAA/AA batteries, no charging capability.

I have a different model from razer (basilisk hyperspeed x) which has got the same issue you mentioned - occasionally the mouse was disconnected and needed to be turned off/on again to get reconnected. Also the battery needs to be 1.5V, if I used a recharable battery which is usually 1.2V then the Razer central software will report it as 'low batter' even it was freshly recharged, and if I keeped using it, the mouse was disconnected very often.
But overal I think it's still a decent mouse.
(I don't know why it doesn't allow me to post without selecting 'associated with Amazon'. I don't know what it is and I'm not an Amazon seller)
