Update: Original review below but after about two months of very infrequent use the adapter started to have problems. For some reason it keeps telling me that the USB stick was disconnected and then reconnects a second later. Occurs in all adapter slots. It's a bit frustrating trying to work on something that's on those USB sticks. It's too late to return an item so I'm stuck with something that has stopped working after very little use. First Rating: Works as it should and really makes up for the fact that Apple cut corners instead of putting the main entrances on their very expensive laptops. My only criticism of this product is that you have to be really careful when unplugging USB or other connections. More than once I've had 2 flash drives and when I took one out the whole adapter came out and closed everything I had opened for another flash drive. It's easy to remember to hold it when you're unplugging something, but I often forget. It's very nice, unlike some others I've seen, that I can use more than two locations at once. I have seen with some that you can only have 2 flash drives or one USB flash drive, charger etc. simultaneously. I can easily have a charging cable, flash drives and an SD card. The fit and finish are the same as the MacBook, so no complaints. Just remember not to pull out the adapter!
