I have about 20 or so in the field... Work great except for 2 issues.
1. One of the pros, I powered 7 ports with 24v and it started rebooting all 7 AP's constantly every couple minutes. Cat5 runs were probably around 200' or so. We took one AP off of the TS and plugged it into a seperate POE injector and the problem went away. Firmware 1.2
2. A very large batch (if not the majority) of TS pro's are NOT grounded. There was some sort of manufacturing oversight and there was a screw not tightened somewhere
. I confirmed the 10 I had at the time were not grounded.
All 5-port tough switches I had were grounded. If you search their forum they provided a fix you can do yourself if needed.
Other then that they have been working great.
