This was my second 1400 opener for my sliding gate. The first one lasted about 6 years. As I was happy with the performance of the original unit, when it eventually became intermittent, I decided to replace it with the same model. Setting these openers up is pretty simple, but the replacement failed to close after about 3 months. Customer service was very helpful in trying to troubleshoot the problem, but in the end, concluded the problem was within the circuit board. They sent out a new board right away under warranty and the problem is cured. Excellent customer service response. Fingers crossed it holds up as well as the original one.
