Its surprising how many powetouch owners praise the after sales/back up, which yes is good, but then the product has BROKEN, or am i missing something?
Had my Reich fitted in 2004, never needed to test the backup, but had to change the pp3 battery in the remote this year.
There are a lot cheaper systems available today, shop round and compare the product before you buy, i compared the powertouch to the reich in 2004, but were about 1 year in use, the reich appeared to be better made, and had weathered the better of the two.
But like i have said, things move on, i would once again be comparing build quality, against price, and warranty.
