I used it on Friday 9/4. TSA agent was unhappy about it and told me he thought it was a "pain in the a$$" to use his scanner to scan my Blackberry. It worked fine though and he compared my ID to his scanner and waved me through.

I was flying to Pullman, Horizon gate agent cheerfully scanned my BB and sent me on my way.

Overall, I will continue to use it as often as I need to. When I'm running late and can check in on the shuttle from the carpark to the airport, it's a nifty time saver.
