I have had nothing but good service from ocz.
Two sets of reaper died, back within a fortnight. Now older and wiser, im fairly sure i was to blame for the first set. Presumably they knew this from diagnostics, but they replaced it regardless.
One of their psus failed too. Red light came on one day, no damage to any components as far as i can tell. They collected it by courier, then a week later, a much better pc p&c turns up. Cant fault that anywhere.
I would love to buy another psu from them, but i think this one's going to last forever. It's now crudely watercooled and has survived discharging mains ac into me half a dozen times.
Finally, when i thought id broken this one, having thoroughly voided the warranty, they offered to collect it for repair or to send me replacement parts foc to repair it myself.
I cannot fault the company anywhere. Long live ocz.
