Putting On

Price

Offers affordability, but can be perceived as thin for the cost.

Can be sturdy, but also prone to holes and tears.

Bought this to cover pool when not in use . Keeps dirt and bugs out ! Heat cover was making pool to hot ! I used cable to hold cover on but did not use cable tighter! Ran cable through holes than tied cable ends together use two bungee straps to get cable to tighten to hold cover !  I disassembled pool for winter storage!

Pool cleaner less evaporation!

[This review was collected as part of a promotion.] I bought this to use to cover my pool for the winter. It was a perfect fit and is holding up well! I have a pool pillow under this as well it is collecting water of course but the material has been sturdy no rips. I am happy with this purchase and do recommend.

Pool cover tarp

[This review was collected as part of a promotion.] I have been having covers tear for the past two years. This cover is strong, durable, and a perfect fit. I want one size up just to ensure I had enough slack.  Even with the overhang it tucks nicely,tightens firmly, and it is a solid product.

[This review was collected as part of a promotion.] this 
Swimline  18' Round Above Ground Cover was sort of what I was looking for. It is very lightweight so it's easy to put on and take off. The only problem is that it is so lightweight, the slightest breeze will blow the corners up and expose the water. I use it to keep debris out of my pool when we are not using it and it does that fine, but if a small gust of wind comes up it just lets leaves and twigs in from overhead trees. 
It does come with cable to hold it in place if you are not going to use your pool for a while but it's kind of a pain if you use your pool daily. I have just been using bungee cords to hold it down and thats works fine.

VERY lightweight

This is not what it thought I was ordering. It does look like a good product but useable for me.  Can I return it to a Walmart store?  I would recommend this only for those who leave their pool up all year.

Pool cover

I have had some wind here the past few days and this item ripped easily.. It is still holding up, I will consider the rips, drain holes, but all in all, you get what you pay for..

Pretty weak..

cover is good but the thing that holds it on is very cheap and flimsy it broke the first time I used it I had to tie the cable to the pool by the legs on the pool. may blow off first wind. would have been better if just had a string or elastic running through it.

very disappointed

This ripped trying to put on the pool and it's been over 30 days so I'm sure there's nothing I can do to get a refund or replaced. It literally ripped unpackaging it

Do not buy this. Made cheap hard to use

This pool cover has a wonky tightening mechanism and came with a cut in it.

Cheap
