I've seen quite a few negative posts relating to Scan's service, so I thought I'd balance it out a bit with my recent RMA experience with them.
In short - it was handled perfectly.
I had ordered a CPU heatsink and fan (which arrived the next day FOC using the Scan2Hexus free shipping ) which I took my time over installing a few days later. However on boot, the fan would not spin. After fiddling with settings in bios and checking it was plugged in correctly, I still could not get any action out of it. So I took it all out and found that the fan blades had sheered off their axle and were only held in place by the motor magnets
Anyway - Scan sorted out a RMA quickly, allowed me to drop off the faulty parts at my local Citylink depot the same day and covered the shipping costs back. On testing it, they found the fault and refunded me the money.
Yes, it was annoying to have a broken part and to waste several hours, but it wasn't Scan's fault and they did everything right to sort it out. Result - a satisfied customer.
