C2G/Cables to Go 29353 1-Port USB 1.1 Over Cat5 Superbooster Extender Dongle RJ45 Female to USB B Male Receiver

very good

This was the recommend extender for the Promethean board that my girlfriend had in her classroom. I tried other USB extenders and none work. This one works like a champ, and was a great price.

Works OK and is constructed well

Worked for what I needed. Just remember you can't connect more than 2 or 3 extenders, or you will not receive data through the line.

Did not work as described. No data connectivity when plugged directly to switch or modem. This did not work for me. I was able to get a refund so thank you for that
