"This stuff is excellent. Have used the plain product by Screwfix, product code 74549, and this product is far better and at a cheaper price, if you buy 3 or more which I did. The 3mm underlay is a very good, firm sponge material of far better quality than the aforementioned. The vapour barrier makes laying length of underlay very easy since this has an adhesive strip that allow you to join adjacent lengths to keep it all straight. The self adhesive is very effective and as I found out its very hard to remove the flooring once stuck down. It allows for small undulations in the floor which is very useful. Flooring is very quick to lay with this product. Will not bother to try anything else after this."
