I use it daily with a Transcend microSDHC 8GB memory card. I bought both together on 29 December of 2010. So already couple of years ago. In any case both parts are working today without any problems and dropouts. The speed of writing is OK for my needs. I had then bought the Reader as a solution for my car radio. For my car radio I use it currently still daily over about 1.5 hours. So more than 8 hours every week. For my MP3 collection in the car it is optimal. Will not miss him. Would I buy again at any time.
