Well the UDM Started doing funky things. Surges in speed to almost no speed and a burning smell. Called and talked to David. He sent a new one out right a way. Good customer service. I was a little suprised when he said Ver.2 would not be out till March 2008. With the switch being a safety issue, I would have thought they would have upgraded the UDM right away. He also said very few have been returned for problems. All in All things are OK. This makes the second one I had to send back. This one has lasted since 7/27/07.......Life goes on. Glad I have a backup.
