No expert opinion on card, it just works as expected. However, de price premium for the USB adapter is only useful if you are looking for an easy and small microSDHC adapter. I was planning to fit the adapter with a memory card and attach it to my keychain, but this is not really possible. The small eye is made of plastic and too small for a ring so it will most probably break easily. Further More, When inserted the memory card sticks out a bit quiet and almost completely Call covers the small eye with a chance of losing it. The adapter works fine, but the key shaped design promises a function it unfortunately does not Fulfill.
