Pool cover held up to windstorms.
Color: Blue Size: 24FT
This pool cover is perfect. This cover installed very easy. It comes with the wire to string the cover to the pool. You weave the wire into the pool cover holes and around the poles on the pool. It did not blow off during big windstorms. We had winds over 60 MPH and the pool cover stayed on. It has quality material. We took it off and cleaned it with a brush. The cover will last for years. We have a 24 ft Bestway pool and it overlapped all around the pool. It was perfect size. The edging on the cover is thick canvas. It held up great too. I highly recommend this pool cover. ... show more

The Hercules of Pool Covers
Color: Blue Size: 24FT
Buy it right now! I frequently write reviews, but honestly, this pool cover is the best - strongest, excellent fit, durability - I've ever owned in 12 years of having a pool. Thanks to a changing climate, we've had extremely strong and frequent winds over the past two years. The '24-'25 pool cover died in the middle of winter. I purchased this with low expectations in September '25. Upon receiving it, the quality was evident in the thickness and feel. By December, it had withstood 4 months of wild winds with gusts as high as 60mph. In March, the leaf cover blew off, never to be seen again, but this cover held strong, even when the string snapped after a gust that sent my full trash can a 1/4 mile up hill into the woods. It also held strong when my 6-seater table blew off the deck and onto it. I wish I had taken a picture of the cover on the many occasions where it was standing 7-8' above the pool in strong winds. No other pool cover has had to deal with the extreme weather that this cover has dealt with, but they generally failed after one year. While this cover will require a new string and has one grommet that tore slightly, I have no doubt it will serve another year. I wholeheartedly recommend this excellent pool cover and will purchase another one this year, just in case '26 fall and winter weather is just as crazy as this winter was. ... show more

Pool Cover for winter
Color: Blue Size: 18 FT
Excellent Protection and Value for Winterizing I couldn't be happier with the POOLHACKER Winter Pool Cover. After years of struggling with cheaper, flimsy covers that barely lasted a season, this one is a serious upgrade. Installation and Durability: The cover feels incredibly durable and heavy-duty right out of the box, which gives me confidence it will handle harsh winter weather, including heavy snow and ice. The installation was surprisingly straightforward. The included winch and cable system made securing the cover to my above-ground pool much easier than expected, allowing me to get a tight, reliable seal with minimal hassle. Performance: This cover excels at keeping debris out. which translated into a much easier, faster spring opening. Less mess in the pool means less time scrubbing and balancing chemicals. This cover truly protects your investment and saves you significant work when the warm weather returns. Bottom Line: If you're tired of replacing pool covers every year or dealing with a nasty mess when you open your pool, the POOLHACKER cover is worth every penny. It's a high-quality product that delivers on its promise of superior winter protection. ... show more

Generously sized, well made cover
Color: Blue Size: 21FT
Very pleased with this pool cover. Well made of pretty thick material with good strong grommets. Generous in size too. We have an 18 ft. pool but we ordered the 21 ft. cover, it practically touches the ground all the way around. Should weather our windy winters.

BEST COVER IVE EVER BOUGHT! And I’ve bought a bunch!
Color: Blue Size: 30' (Round)
I have had an above ground pool for 30 years. This pool cover is the best one I’ve ever had. I cannot give this more stars than five but it deserves 10+ stars. I usually buy a new cover every year due to damage, grommets torn out, tears in the cover etc. this cover survived this past winter without any damage at all. I live in a field without any wind break, this cover domed up with wind and flapped in the wind, had 1-2 feet of rain water on top along with leaves and whatever the gale force winds blew onto it. Even when the water on top froze and the outdoor cats had a great time playing on the frozen water. I 100% recommend this cover. I’m a 65 year old woman who puts it on (with 1 or 2 extra people to help hold it due to wind) when I close the pool and i take it off off alone, fold it and drag it thru the yard to the garage to store till next time. It’s in perfect condition and will be used again and again. The edge where the grommets are have a canvas marine like fabric binding which will survive for several years. Love it!! Don’t hesitate to purchase it! ... show more

Terrible cover
Color: Black Size: 12' (Round)
One of the worst designed pool covers you can think of. There are no water vent holes, if it rains you are screwed and either need to dump all the dirty water into your pool or lift very heavy water filled cover out of your pool. Also the wire this thing comes with to tighten it is the craziest design ever? Why wasn't a basic tie line just implemented into the design of the cover? What's with this crazy wire??? Put this on my pool once, took it off and getting it back on with the aluminum wire didn't go well and I ended up refunding this thing... ... show more

Best cover I’ve ever bought in fourteen years of covers.
Color: Blue Size: 24FT
This is the absolute best cover I’ve ever bought. Opening the pool this year was a breeze. This cover is thick so it doesn’t allow the pump on top to suck water through it. So I didn’t lose as much water as I normally would with the automatic pump on the cover all winter. Water was crystal clear. This is my go to cover from now on n. ... show more
