Our team has been using them reliably both this year and last year. I don't recall having any real problems with them.

There has been about two times when the download has stopped halfway, and the PBASIC editor gave me a hardware communication error. But other than that, we've never had any problems.

The biggest thing though: make sure the robot stamper is the correct modem (not the regular robot controller modem), that it's plugged into the program port, and that you have it plugged into a PWM output so it can get power.
