I have a WH1091 whose remote unit eats batteries. I have had no response from FOSHK to repeated emails. Thinking of upgrading (?) to the 3081 but after seeing your comments, I doubt whether there will be any advantage.
I will have a look at other brands and pay a bit more for reliability. There is an Omnipad PRO R4 which is more expensive but looks identical! Anybody got suggestions?
