Am using this to transfer recordings from Humax PVR to PC hard drive while I partition new hard drive. Has worked faultlessly so far - 2 months (I haven't yet got round to partitioning!!) - with no problems. Only slight downside is that it doesn't have any sort of cover so I wouldn't want to keep it loose in a pocket as dirt/dust would get into the opening. I therefore keep it in the original plastic packaging.
