Everything about my transaction with warmyourfloor was excellent. I had looked many products available - from loose wire to other mats - and kept coming back to SunTouch - as I wanted to install over cork for a thermal break from the concrete and they promote that for this product. Warmyourfloor was very helpful with the layout drawing, and in my odd shaped bathroom this project would have been very stressful without it. From my drawing, they calculated the sq footage I needed and how to layout it out. The mat itself laid out easliy and stuck well to the cork underlayment (over concrete slab). I used a little extra double sided tape on the mat and a lot of hot glue on the loose wire portions. My tile guy decided to totally cover the mat in thin set, since that is how he leveled the room - so it was a 2 day process allowing the skim coat to dry. Even with the additional thickness over the mat, it heats well and feels great. The thermostat is great and much better than the one I used previously in my kitchen loose wire installation.
The wire and the connections all seem very solid and well made - nothing seemed cheap - which is good as it is buried under a lot of thinset and tile! I did put in one backup thermostat sensor wire - cheap insurance!
