The ad says 400 microns, after checking in two pool stores it is clear that this bubble cover is 200 microns. I am not happy with the answers of the seller, very light and weak, they say "our price is great", but I preferred that the product is exactly what they say on their advertising, the more they say it will increase tarpaulin the temperature of your pool by 8 ° c ..... not !! I had my pool for 10 years so I have a bit of experience!
