Very good stick, unfortunately unsuitable for Keychain

As for the performance of this USB stick, I can join most reviewers here.
The data transfer is compared to other sticks very quickly, the processing is at a high level.
The click mechanism is reliable and error-free and is a nice gimmick.
I have (ie approximately 11 months) carried the stick since May 2010 on a key ring and had it in daily use. Unfortunately, the thin web is now but broken at the top, to which a small key ring could be fixed. Therefore, it is unfortunately no longer be used for this use now. Too bad, because the Swissbit I previously had on a key chain, has been through the use of more than 5 years without any problems.

I will now probably use the stick for data backup and purchase a Swissbit for daily use again.
