Hi Dave They have sent me a replacement unit FOC but on the understanding that it has no warranty. You can see that they have sent a tweet, but I don't use twitter. My telephone number was on my original message, so they could have contacted me.
We have another one now that has a problem with the connection to the circuit. It will be interesting to see what the outcome of that one is. We have quite a few of these units here and I'm wondering how long they are going to last.
Regards
Richard
