Great service - very knowledgeable staff on the helpline - advised of exactly which item was compatible as a replacement for an obsolete stat, and prices are very competitive too. Also delivery was perfect as arranged. All in all excellent, and will definitely use again.

Mat does not appear to be as sticky as a previous product

Your service was quick and efficient. My concern was with the DEVI product information and installation information. I have previously fitted a DEVI mat however the installation information was minimal and no explanation given for the pack content. Fortunately I remembered most of the installation steps. The one that I didn't was answered by DEVI customer help. My point is that the product is good but the installation information is poor as is the online information. If DEVI ask you can feed back this information to them.
