Rhino BaseMate 18" Umbrella Base Weight – Fits Offset, Cantilever & Outdoor Patio Umbrellas – Detachable Design – Black – Easy Setup

Why did you pick this product vs others?:Our area frequently experiences very high winds that blow the covers right off our patio furniture (fishing the sodden covers out of the pool is a special kind of "fun"). I got these to weigh down the the patio dining table cover, and they are just perfect. We filled them with 25lbs of sand each (note they can hold much more), and placed one at either end. The form factor isn't right for our umbrella base, and I had initially thought a cloth weight would never stand up to our desert heat anyway, but these are MUCH thicker and sturdier than, say, Sunbrella fabric, so after seeing and using it for myself, I think they'll stand up to just about anything.

Seemingly strong fabric, even when filled with sand. Did not feel like it would rip when I had to move it multiple times around the yard when finding the right place for my umbrella. Like other commenters, I added one sandbag (the whole bag, not loose) into each of the two weighed bags. There's handles on the bags to make moving and positioning them easier. There's also hook & loop on the side with the pole notch to attach each bag to each other.This brace weight will work great for most round bases. However, for a crossbar base, you should do the following, to get a sturdy and solid foundation. This assumes your crossbar base has the bottom lips where you would normally attach them to the ground with bolts. First, get yourself some concrete square step stones. At minimum, get two. But since you're there, get 4, one for each side. They're cheap. Put each of these on top of the lip of the base. Now you've made yourself a nice movable base. Next, put these bags on top of the crossbar. If you've filled the bags with 50lbs of sand, along with the stones you'll have about 300lbs altogether keeping this thing down. And moving won't be a problem since you'll just need to move 50lbs at a time.Pros- Bags seem sturdy and don't look like they will rip. Time will tell if the weathering will cause these to disintegrate- Handles on each side make carrying them and moving them a cinch.- Big enough not to cause any problems when filling with 50lb sandbags without taking the sand outCons- Made mostly for round bases, but can be repurposed (see above) for cross bar bases- If you have a large cantilever umbrella, the 100lbs that this can fit (2 50lb bags) may not be enough. See above for tips on reinforcing with step stones.Overall, this fit my purpose. We were hosting a little kids party and I had to make sure the umbrella stayed put even if some sugared-up kid decided to mess with the umbrella. The combination of this weight and the stones made sure of that.

Worked fine. Put full sand bag in. Tight fit but its holding my umbrella.

Very good and easy to use product. Stabilized my umbrella easily.

This is such a great idea. Very sturdy with a zipper. 2 pieces so you don't have to disassemble the umbrella. You can fit a 50 lb bag of sand in each piece. These will last for a very long time.

They look nice until you start trying to fill them with sand to get them to look like the pictures. They would some hard siding, otherwise they do not look good. As to how effective they, I have not the opportunity to test them yet!

These work great. My umbrella doesn’t move. Each hold 45 lbs of sand. Love the waterproof

As advertised. Strong construction and fills easily. Make sure you have it where you want it when you fill it as very heavy.
