FYI, my $80-90 Razer mouse from a couple years ago broke recently. It double-clicks instead of single-clicking, totally screwing me up on numerous occasions (moving, renaming, deleting files; issuing orders in games; performing actions when not intentional).
I thought it would be a mouse for life. I treated it like a baby, never touching it without perfectly oil-free hands, gently clicking it, not letting anyone else touch it.
I had a generic $5 mouse that lasted me about 4 years of heavy use. Razer's craftsmanship is weak and is definitely not proportional to the cost. Not hankering to buy another mouse from them.
Had the same problems with Razer mice myself, only they would manifest themselves within 30 days to 6 months after purchase. I've used dozens of Logitech mice over the years and only two have ever had issues. They were both replaced with zero hassle. I like Razer's gaming mousepads, but I will never use their mice ever again.
