Leaks Review by Gary
About a third of mine leaked. Pin holes can be found on the bottom from the mold process. I have had to patch pin holes myself. If not for the leaks these would work just fine.
Blocks Are Worse Than Tubes Review by Michigan Pool Owner.
I have always hated filling the tubes, so I ordered 2 boxes of the blocks for our pool. Half of the blocks and/or covers in one box were cracked or split where they had come out of the mold. (The box was not dented, so they must have been packed that way.) Doheny's promptly replaced them.
The blocks are very fragile, especially for use in a cold climate. Just bumping into one will crack it. The lids will not stay on and they blow into pool and tip over. I have half of the blocks left (I just ordered this season) and had to supplement with old tubes. This product should not be sold!
Water Blocks Review by Dominick
This item is the worst I've ever seen. Doheny Pools should be ashamed to sell an item as cheap and poorly constructed as these are. This is the kind of product you'd find at Walmart, not a pool supply company. If I could give this rating a negative star that would be more appropriate. Save your money, don't buy these.
Poorly Made Review by Frustrated
We purchased 24 boxes, when they arrived 7 lids were cracked and one box broken. For the price I assumed the plastic would be thicker. Full of water they are easy to move. We are going to fill these with landscape bricks and hope for the best.
