## Customer Reviews

### ⭐⭐⭐⭐⭐ Easy-ish install. Just pay attention to the instructions.
*by J***E on November 27, 2018*

I have this product installed in a kitchen/breakfast area. The area is about 300ftsq so I have it divided into 2 zones (2 thermostats). 2 key points are to be sure you use the correct mortar for bedding the mat and for setting the tile. It calls for unmodified mortar for the tile, which is a money saver as its usually the least expensive mortar. Some mfg have brought out “membrane” mortar, which is what I used (mapei). Keep the mats lined up to make the cable install easy. And watch the wire spacing. More than once I had to pull up and re-route the wire because I didn’t pay attanetion to the spacing recommendation (amazing how well it worked when I read the instructions). Wiring was simple once I ran the 2 dedicated circuits to the thermostats. I waited 7 days before starting the system and then no problems. It takes a little trial to set the correct temp for the floor as to not be too hot and overheat the room.

### ⭐⭐⭐⭐⭐ fast delivery
