So this puzzle mat you have 2 days in use and I must say I have more presented below! The flow is not exactly of the best quality, it had first of all iron as he had wrinkles on which individual pieces were not lying! That was not so easy, because you had to be very careful, because the temperature of the iron !! But after the folding problem was eliminated! Now she is on parquet floor and as soon as you slip it "pushes" away, so again overturn parts quickly !! In short, I would have liked a little stronger material! The cardboard tube was actually a little hard to roll along, but it went! The puzzle I have not so rolled Wenns works not a bad idea !! If you consider that the mat has cost 15 euros, I would say value for ok! Whether I would buy this mat again ???? Etc. A large plank of wood I would prefer !! However, this could not "put away" so easily "!!!
