[This review was collected as part of a promotion.] hi all . I want to leave my review about the part that holds the large umbrella. This 34" Square Durable 2-Piece Umbrella Base with Rotating Wheels for Patio and Pool Supports an Umbrella up to 11ft Long. Unfortunately I don't have an umbrella at the moment but that's not a problem because we were planning to buy one for the backyard. Square shape. The material is black plastic, it is strong and seemed a little heavy to me, since I was pulling this large box myself, I could use some help. I took everything out of the box and found instructions that mentioned this holder. There are 3 holes that are fixed with screw caps, so that if you, for example, want to fix the holder for an umbrella and so that it does not spin around and go all over the yard, you unscrew the hole and fill it with water and then the square solid base costs a lot it is firm and has an emphasis. Water tends to evaporate, so add water at any time and you don’t need to worry about the movement of the umbrella clamp. I liked the fact that you can remove part of the roller wheels from one side and insert them on the other side and move it to the place you need. At first I thought that there should be wheels on both sides, but then I read that everything is correct, there are wheels on one side and they can be easily removed. A very interesting thing for home life. Our weather is different, and the umbrella is sold without a stand; you can’t just stick it into the ground. but there will be no problems with this stand. We poured water and screwed the umbrella to the central area. there are holes for the umbrella screws and that's it. the umbrella stands on the platform. I recommend. a great option for solving the problem of where to insert an umbrella. Compatible with an umbrella, this is a super couple or blowing that each other needs in the household
