apparently it's a mouse. I bought it to replace my old Abyssus because the clicker stopped working, yet again (no, I didn't abuse it.)

I'm not fond of it "forcing" me to use this Razer Synapse software to change DPI/polling rate/&c., but I haven't had any issues with it so far. unfortunately, it doesn't seem to let me select 450dpi, which is what I was using before? unless the very sketchy "in-betweens" are actually incremental values, I only have the option of 400 or 500.

and this doesn't translate at all to the mouse feeling I had before in Quakelive, where I was using in_mouse2, no acceleration, and sensitivity 3.5. I've had to up the sensitivity to 5+ for a similar feel. what gives? any ideas?
