No problems with the hähnel (the battery issue was obviously a wetware problem), it works reliably. The only annoyances are related to auto-off timeouts – the transmitter shuts off after only 1 minute (adjustable), and the receiver doesn't seem to time out at all (meaning the battery dies in storage, and it's an LR2 not a 'standard' battery).
I had the hahnel in my cart and was about to order it, but at the last minute I changed my mind and switched to the Vello. Live and learn.

As for the battery on the hahnel, I am notorious for not turning things off. An auto-off seems like a good idea. It saves the battery on my camera a lot.

Thanks for the infomation. I will have to look into it again.
