Outsunny umbrella base
Great product and even greater customer service!!!
Purchased along with umbrella
Purchased along with the 10' umbrella for much needed stability. Keeps umbrella unit grounded. Fits perfectly around the base.

Very unhappy
We purchased this set of weights as recommended, to fit the cross base that was supposed to be included in our parasol order, but it was missing.

These are now useless to us due to the missing cross base and we can not use the product from day 1 because of the mistake of AOSOM. This is very frustrating because no one from AOSOM is trying to help, it has been very difficult as we are not asking for a discount, we need the product we purchased.
delivered different day than Umbrella but good with way too large for size of item. Not assembled onto base of Umbrella yet but looks easy enough...stay tuned :)
Great quality! Great purchase!!
This product is absolutely amazing! Super sturdy and a great value for the money spent!! This piece looks great in my yard with the rest of furniture I purchased for my yard to enjoy this summer!
