junk
Would Not RecommendI bought 28 if these and all of them fell apart before I put them in the ground. we had a light overnight rain and I woke up to seeing this! I have 500 dollars of junk and the building inspector that afternoon for inspection. i needed to cut the ends losing up to 16" and bracing the top of the tube in 2x material to keep it round. I am hoping a rep from lowes or sakrete sees this and reaches out to me. disgusting quality control.

Maybe the best concrete form ever made?
Would RecommendI'll never use a different concrete form ever again. This is all the concrete form I will ever need in my life.
It does the job!
Would RecommendIt’s does the job just fine. If you are looking for above ground precision, don’t use these, as they are not all the same diameter. Great for fence and deck foundations.

Would RecommendThis is a great product for the value. Easy to use and install
A little lighter weight than I expected, but will
Would RecommendJust what I need to wrap around a support for a deck and fill with concrete. I will have to be a little creative as I cannot remove the support. However, the tube will be easy to cut, install around the 4x4 support, retie with wire, and then fill with concrete. Looking forward to get it done.
Awesome
Would RecommendAwesome experience, everything arrived on time as expected. Good quality.
Solid form used for deck footings
Would RecommendI used this tube form in my deck project. It provided excellent support during pouring and curing. It was pretty easy to work with. The result was strong footings, laying a solid foundation for my deck.
