howdy , yeah ive used them maybe twenty or so times , they are seriously insanely cheap, 90% of the time super fast , have never had damage , twice a tad slow but really when you price around you just cant beat them by a long shot , when they were slow ' finally ' i got a ck[ontact number and their response was instant and rectified the problem , i wouldnt even bother get other prices , ego are ' the goods ' , cheers pete
