High Quality Fabric not a tarp.
Size: 18FT x 18FT x N/A Color: Black
Really like the product. Have not gotten into the season yet, so not sure how it will handle the snow yet, but first impressions are good. This is not a tarp. It has a very strong material and is stitched together so should be sturdy. My tarp style last year ripped in two at the seam so this is important to me. It came with some velcro strips that were not as long as I thought they would be, but I cut them in half to make more of them anyway to wrap around the legs. The ropes and steaks are not worth it in my opinion, the wind will just rip those nails out of the ground in a second. But you could use some stronger ones if you wanted. My only complaint is I have a 16' pool and this only comes in 15' or 18' so I am over the edge quite a bit and things don't line up exact, but the functionality is still good. Hope to use this for seasons to come. ... show more

Best pool cover!
Size: 15' (Round) Color: Black
We've purchased so many pool covers that don't last with the weather. This cover is strapped to the above ground pool and anchored in the ground. It's going nowhere and has even withstood a few storms!

Didn’t fit
Size: 15' (Round) Color: Black
It didn’t fit the pool. It kept blowing off, but then we used it as a tarp underneath one of our tents and got good use out of it that way.

Takes some pooling back and forth for a good fit, works great. The material is strong

Good product
Seems sturdy and works ok. Only has 4 tie down spots so when it rains it falls in. Can’t get the string tight enough. Needs a rope that wraps around. Had to put a prop stick in the pool to keep the water from pooling which is probably the issue with all soft covers. So with slight modifications it works good and is a good price ... show more

Works wonders!
Size: 15' (Round) Color: Black
We love this pool cover, it completely covers our pool and very easy to use. It is very light weight and easy to remove too. We have a 14 foot pool and it covers it completely. If you need a good pool cover that helps warm the water this is a great product.

Great Cover but needs drains.
Size: 18FT x 18FT x N/A Color: Black
This is a great option for covering your pool. However, if you don’t want it to sag you need to burn a few drain holes in the middle. Don’t make them too big so debris doesn’t get through. Otherwise it’s great. It fits my pool unlike other covers I’ve used in the past. I have an 18 ft round pool and it comes over the sides approximately 2 feet! It was easy to install, my old covers took myself, husband, and two kids to put on, I put this one on by myself. ... show more
