Great News! Thanks again.
Me and my wife have been double and triple-clicking happily for about two years now with ACT ZDW232's. I had some battery powered wall controllers but, as they had different look from the ACT ones, she didn't want them... go figure
The trouble with ZDW232's is that they break down really easily. About 50% of them broken in the first year and now they are discontinued. We got used to the system and would now like to replace them with something similar.
