My husband had installed the mats before so we were a bit timid. The price was so tempting we went with it. Amazing ease! We used dry wall tape, not the harsh metal securing they sent. Make sure you measure! The end cannot be cut! So, you cannot have too much cable. Haven't really had a chance to use it yet but we're quite happy so far.
I'm very impressed with the quality of these products. We asked a contractor to install it and are very satisfied of the results: it works perfectly fine! I don't think we would have been able to do it ourselves but the contractor was pretty fast... Overall, we're happy!
