We debated for a few days about whether to go with the radiant floor heat wire, or the mats, to go in under a thin layer of concrete to level out the grade of a former patio concrete slab, with tile on the concrete. In the end, we went with the 120 sq ft of wire. We are so glad we did! The instructions say that you can space the courses 2.5 - 3.5 inches apart, and to stretch it a little further we went with a fairly consistent 3.5" spacing pattern. Using a bit more space between courses covered WAY more than 120 sq ft.
We felt like the metal straps that came with the wire were a little cheesy, not to mention a little sharp, so we anchored the wire to the (clean!) concrete exclusively with hot glue. The hot glue worked like a charm. It took about 6 hours start to finish to pull measurements and install/glue the wire to the floor. We also took the advice of another reviewer and installed a spare sensor, because $10 sure beats ripping up tile and concrete.
My partner is an electrician, and we used a meter to test throughout both the setting of the wire and the concrete; we concluded that the wire is tougher than we thought it was (though we were very cautious not to step on it, set/drop things on it, etc). If you don't have an electrician's meter to test periodically during installation, the loudmouth seems like a worthwhile precaution.
The only reason I didn't give this 5 stars is because.... we haven't laid the tile yet, so haven't tested how well this stuff actually works, but I hope to be able to add that edit to this review relatively soon.
Overall, we are very happy so far with this stuff.

Rated 3.0 out of 5.0 by russ Installation problems using metal tabs
The product works as advertised. The metal strips that are to hold the wire on the floor are pretty useless. Stamped out of metal strap material the tabs are very sharp and could cut the insulation on the wire. Hot melt glue would be a better solution followed by floor leveler rather than thinset. Too much danger of damage when working the thinset. SunTouch says not to use leveler with a framed floor but couldn't give me a reason for that limitation. Also the metal straps raise the wire up too high... all must be covered with thinset.
