Have I bought the stick for the keychain when Always-In-Stick. I wanted a with sliding mechanism to protect the contacts. Unfortunately, this is far too easy for the stick. Most keychain in your pocket the sliding mechanism does not hold a few seconds and protecting the contacts is no longer guaranteed. For this, the drive is also quite slow. Overall, therefore, not as the yellow of the egg. Only recommended if you need reasonable space and the speed does not matter.
