product very very very disappointing not being slow. tested with several Class 10 card which I have personally tested the speed 16Mbs + + 19Mbs writing and reading. Maps a time inserted into the adapter their speed of fall to about 2Mbs 8Mbs writing and reading. If you like you intend to install an operating system and then go your way then drink several dozen cups of coffee to stay awake. it works (so I can not return it) but it is unusable unless you are a masochist !!!. Besides I uninstalled the product. A star that is too I put only the speed of delivery not that of the adapter. Maybe I am falling on a map whose components are of poor quality ???? if its software is serious because all these adapters are in the same situation ... but not the experience I would do to check that this product is especially dear to his pitiful performance ... to flee.
