Despite all my issues with the Wunda system, LVT and the Mobile App I cannot fault the customer support that is just brilliant and moves them from a one star to a three star.I am currently in DIY hell with the Wunda system. It might work for small areas but I cannot recommend it for large floors, particularly if you are planning to use LVT.I have spent 14 full days on this, and still do not have all the panels down. I have used 26 cans of adhesive. I described it to someone as doing a massive build your own jigsaw. I still have three of four panels that have some movement so need to pry them up, almost impossible without breaking and glue down again. I got three different types of adhesive from Wunda and the issue is with those that had the clear adhesive (others are green and blue). It turns out that for LVT you have to fill up all the channels not used by the pipe with self levelling (and not the cheap stuff because it is going onto the insulation boards). There are a lot of channels, you will notice there are no videos covering this and no way to calculate how much additional self levelling you need.Other issues:1) No videos show what to do around door ways2) No sizes given for panel cuts but you are expected to use parts of panels in other places, no clue to what and where3) Static will keep shocking you as you handle them4) I have really struggled with the clear glue and green Wunda branded glue. The blue one seems a lot better
