Robelle 3811--12 Pool Cover Weights, 12-Pack, 10 ft. Blue Double Chamber, 16 Gauge

Had to have replacements this year, ordered these. Wow the price has really went up but they do work well!

10-for-10. All tubes still full after 7 weeks. Maybe I got lucky? Very happy with these so far.

They work as well as any other water tube. Easy to fill and close. As durable as the ones my pool people provided but much cheaper. However, if there is a windy storm and branches fall at just the right angle, it will still poke a hole in it. That's just the casualties of using the tubes unless you get the real heavy gauge, I guess. I like the 10ft length, I find the 8ft is a little short. Overall, I'm satified with it.

This will be the first winter that I use water tubes to hold down the pool cover. In the past I've used heavy and smooth paving stones. Soon after the tubes arrived, I decided to try out one of the tubes. One of the chambers leaked. Today, I pulled out four more tubes and had one more leaking tube, So that's 2 out of the first 5 tubes leak. Now I need to decide whether to try out all the tubes, which I really don't want to do right now, or just send the whole order back and try another brand. Disappointing !

3 bags leaked during the first filling.

Half way through winter half of the tubes have leaks and are empty. Cheap material. Seams split. Plug is a pain to shut. Keep shopping for a different product.

Pretty disappointed with these. I filled all the tubes and two of them won't hold water. Couldn't even fill them up cause water just kept coming out from somewhere. The ones that are holding water are doing their job, but I can't imagine that all of these are going to hold up over the winter. I fully expect all of them to be leaking by the spring. Now I have to find a way to get a hold of customer service to see if I can get replacements.

We just bought the bags and the same day we filled them up 4 bags ripped.
