As I wrote in an earlier article, I really like the KeySmart key system, but being a trainer, I also have a need to carry a thumb drive of my presentations. Luckily there is a Keysmart USB drive.
However, this solution is really expensive. They have a huge markup on the flat USB drive and the adapter that allows it to fit senselessly into the KeySmart.
Their system uses a Kingston Digital DataTraveler SE9 64GB USB 2.0 Flash Drive. I really like these small drives.
They run about $15.00 on Amazon. The adapter costs nearly $10.00.
I found that a simple rubber bushing from the hardware store costs less than $1.00.
I just took my USB to Lowes and compared the bushings until I found one that fit. This is a simplie thing to do, and it makes work so much easier.
