The mat was really easy to install.
However I ordered extra temperature probes. It wasn't obvious to me that the temp probes weren't built into the mats. It was a near disaster until my electrician pointed it out. We worked it out, but I would recommend that WarmlyYours makes this part more obvious for the DIYer. Otherwise it was a snap! The floors are working beautifully! We love them! I loved how quickly WarmlyYours provided the schematics for the the floors we were planning. The turn around time was less than a day. I would definitely do this again!
