I absolutely love this item. The key holder is great on it's own but the USB drive comes in handier a lot more often than I would've thought originally. The strap is real leather, not the fake junk most things are made of these days. There is an instructional video on the usb stick on how to set up the key holder if you need it, though it is pretty self explanatory. MAKE SURE YOU KEEP THE RUBBER RINGS. I lost mine in the excitement and so I only have 3 of the 6. but they still keep my keys nice, they are just a little looser than I would like. But that's my own fault.

The usb drive reads with no problems in mac or windows as I have tried it in both and it's transfer rate is nice. The only thing I would like better is if my car's chip key would fit inside the holder, but it attachs nicely to the metal ring on the outside. I could not be happier with this item. Well done.
