I ordered this tank 2 times thicker than conventional tarpaulins to have better results, but I had not thought of that, 2 times thicker it would be 2 times heavier. I'm a woman and I use this sheet to my above ground pool of 3.70 x 6.10 x 1.32 m, and I must admit that without reel, I have great difficulty in putting it off and alone. So if you plan this purchase, you either have a nice husband with big muscular arms, a reel. That said, the quality of the cover is not comparable with a simple tarpaulin 180 microns. In conclusion, I am very satisfied with the product and speed of delivery. I recommend the product and the seller.
