Makes moving your umbrella around a breeze.
Size: 100LBS
This is best idea in umbrella stands. Decent price. I love that the water intake/release is on the side. Many are on top of the stand. Doesn't leak. Easy to move around and easy to put together with the included tools. I have 2. One for a very heavy 10 x 6' umbrella, and the other for a very light 1/2 round umbrella. Works equally well for both. One tricky part the instructions don't include is that is parts F and J are 'in place' in the base and you need to remove them to re attach them to the cylinder, or what they refer to as the "stand pole". So, if you are looking for parts (and I did this twice), just remember you will find them on the underside of large plastic umbrella base. Both are black, and so not immediately apparent. Love that there are two locking wheels and they include an extra screw. IKEA could learn a few things here.

Hold my umbrella & watch this!
Size: 100LBS, Size: 100LBS
This product does a fantastic job of keeping our umbrella perfectly vertical. We previously had an all metal one which cost over $100 and fell over all of the time. I love the fact that it can be filled with sand and water to ensure it does flip over! We opted to just use water and it is performing flawlessly! The wheels make it easy to move or they can be locked in place. The assembly was very straightforward and took about 20 minutes. I would buy another one if we need it for our second umbrella.
