I had an Asrock motherboard and a GPU (can't remember brand) go bad on me a few years back it became faulty and after testing it for a bit found it was faulty. They asked me to send it to them which i did they "tested it" and said it was not faulty and sent it back to me (at this time i had to pay for both shippings since it was deemed not faulty), i complained after getting it back as it kept giving me blue screens and they were like "we tested it and it was fine" anyway i asked for the distributor of the parts details, they gave me their details, phoned them up, explained my situation and they said i can come on through and they will test it for me and make a decision.
Went to the distributor and they stress tested it and another part which i assumed was faulty too, they said both parts were faulty and replaced them for me.
I enquired with Wootware about my delivery refund as the distributor deemed the items faulty, and they just said "at the time of testing with us it was not faulty"
Left a salty taste in my mouth BUT i will use them again even after this since their pricing is generally a lot better than other places and its local.
There is a second bad review on them
