This sand anchor works great. I filled the anchor with rocks instead of sand to give the anchor a good test. The anchor held true and kept two boats from floating away. the only problem I had was with the handle. I lifted the anchor with the handle and the closure and the handle ripped off, but the anchor did not leak

We are using this item for the third summer to keep our inflatable swimming dock in place. The foam float didn't hold up over time, but everything else has held up very well being submerged in the lake for 3 summers. Very happy with the product.

Trash. Both bags ripped apart first time using.

Works great for the ocean

Started ripping at the top after a year of weekend-only use. Still works if I fold it down properly though! For reference, I make my kids fill it with sand every beach visit, and we keep paddle boards and floaties tethered to it in about 3' depth area on a lake. And yes we sit on the floaties or lay on the paddle boards while they're tethered and it keeps us in place!

These are pretty neat. Take up very little space to pack in a boat, and easy to put to use in no time. We used them to anchor floats and tubes/water chariots when not being pulled. The floats stayed anchored on the lake for a week-long vacation. They never budged. Last day, just pulled them up and dumped water out, rolled up and stuffed under a seat. Done. Very handy.

I love that this anchor is so portable/small and light when not filled. It worked perfectly off the beach of Lake Michigan to keep our 2-person inner tube stationary as my husband and I relaxed on the water! We tried the inner tube without the anchor first to see how far we would drift, and in a matter of 5-10 minutes, we had drifted probably 1/4 a mile from where we had gotten in the water and on the tube. We walked back to our beach spot and easily filled the bag with damp sand. Once back in the water, we lowered the anchor into the water and it kept us stationary, peacefully floating in the same spot, until we were ready to go back to shore. I definitely recommend this product!

Upon first use of the product, one of the bags broke and was lost in the ocean. We used these to anchor a float at the beach on nice day with normal level waves. We had one float attached to each bag and then connected the two floats together. Luckily the two floats were connected together because one of the clasps broke on one bag which would have left the person on the float to drift away if it was not attached to the second float. It was great while it lasted, but unfortunately, we will not be using this again in the ocean.
