Buffalo Blizzard Blue 8-Foot Long Double Chamber Water Bags | 6 Pack | 22-Gauge Heavy-Duty Vinyl Material | Secures Winter Cover to Rectangular Swimming Pools

These tubes last longer than one year. What I don't like is last year I bought several of these tubes at a great price I thought until I got them and half of them came with defects. Looked like they were manufactured as long continuous tubes and they are cut at the end of each length and the ones I got had been missed cut into the seem. I should have sent them back but I love 30 miles from everything. Amazon used to have returns picked up at my house by UPS but know even though I'm a prime member they want me to take returns to a UPS drop off. Inconvenient!!! The picture I posted is of an older tube that has held up more than one year and I think my mistake was trying to buy a deal. All the tubes I bought this year were all good I'm happy to say.

not very well made

Good product, but water leaks on all of them...in the end, only one tube is what actually keeps the cover from flying away.

The media could not be loaded.  Price was right and they feel thicker than the ones I by at the big box store but one had a leak so I was disappointed with that.

Of the 18 we ordered we used 12 this year. Of the 12, one had a leaking seam and the other 11 were good. I contacted the seller and they immediately sent a new one to replace the defective unit. Great response and communication from the vendor. So far these have worked great this year. I filled to about 2/3 full to allow for any freeze expansion. We have a 30' round X 48" deep above ground pool and I have 12 of these slightly overlapping on the inside of the rim sitting on the tarp. We have had several extended occurrences of winds steady 30+ mph and these performed flawlessly. We live on a hill and there are no obstructions so the pool/tarp sees the full amount of wind. This weekend we had severe thunderstorms with winds 60+ and these rode it out like a champ.Update. Just took the tarp off the pool for spring and these worked great all winter. They were frozen solid several times and they all were still holding water great. We had about 5” of water on top of the tarp along with leaves and other organics so there was some algae growth. The algae was growing on the tubes but not to it. They rinsed off with a hose no problem. They were all still very pliable and should be usable next year. The plugs are still solid too.

on of the bags had a huge hole around the fill valve. the others so far seem ok.

many of them half poked somehow. didn't even make through the 1 st yea

dislike the fact that a tube was leaking right out of the bag.
