I was a bit unsure because of conflicting reviews, but I have the Comag SL 40 now for almost 2 1/2 years and can not complain. In the beginning I had a problem. When I wanted to disable the switch-off, went only once nothing more. But other buyers have had the problem and detailed instructions to correct the error had written in her review, I was able to help me very quickly. I had sent an e-mail to Comag and get three days a helpful answer - so to resolve problem in any case. I get along so well otherwise to the receiver and he does everything for the price, what I expect, I have bought two months later one for my daughter. Otherwise I can not understand the many negative reviews on the remote control. She makes a strong impression, is sufficiently large and is still working as the first day.
