We used the umbrella anchor with a beach umbrella and our Sunbrella, worked perfectly with both devices.
It worked great.
I have another one of these but it's a little smaller (it works great) but i like this one better, it really works on gusty days on the beach.
Have not had a chance to use it yet, but it is very well made.
I use this for anchoring our sea doo and works well.
So it takes a good bit of effort to bury it in the sand, and it still comes loose.
Unfortunately when I went to use this the anchor it did not fit the umbrellas I bought so I was unble to use it when I went to the beach.
The augur blade does not extend to the tip of the anchor so you are just forcing the first 2 inches into the sand.
I would not even give this product 1 star.
Would not go into the sand at the beach - tried in various spots.
