(2 stars) Not that great!

By: ssquire
We needed the product to work @ 57600 Baud and we simply didn't get near there! I tested it @ 9600, 19200, 38400, and 57600 Baud on a 256 ft Cat 5 cable. Only 9600 & 19200 worked successfully.

(5 stars) worked very well, stable and consistent

By: pneill
we had a cat 5 run over 500 ft that ran from our hospitality front desk serial interface to the restaurant point of sale server, easy to install, i did use the power adapters as it was convenient to do so... worked very well, as advertised, would use it again.

(5 stars) Works well for our needs

By: Engsup
The extender was purchased to control a camera on a tower outside our broadcast facility. The cable run was over 500' from the Control Room to the top of the tower. Installation was easy and the extender works great.
