“Ordered two of these, both work well. On one of them the slot for the microSD card is a little tight but given how small the card is it's probably just a case that you have to angle it perfectly for it to slide in smoothly. Once you realise this the card slides in fine and work without issue. One is to hold my previous boot card (Raspbian Wheezy) while I confirm all the data I need is transferred to my new Jessie install, the other is for general use in the future. Much better than having a whopping great multi-card reader sticking out of the tiny RasPi all the time.”
