Anybody on here using Icotec callers?

Alright anybody have one of these and like or dislike them? The price is right and they have a incredible range on the remotes.

I tried the 500 and it worked ok. I already had a foxpro and didn't want to have to maintain 2 sound libraries. I have a friend who had a 300 and the hum at full volume was intolerable to me.
