Very Good
Was apprehensive on the boards but stuck on a concrete base in my kitchen with flexi adhesive,Heat mat 200w, self leveller, anti crack mat then tiled in porcelain. Turned the thermostat on after 7 days, set on my iPhone & instant heat at 20degrees increased day by day to 22 and is nice & warm on the feet. Maybe wintertime I’ll take it higher but it’s took a very cold ground floor kitchen to a very nice pleasurable place to be. Thanks Nassboards will definitely be using again 👍👍

Didn't really work for what I needed them for
Bit thin & bendy depends what you using them for there no good for putting tiles over because the tiles move
