The base  is not very strong, and  it was windy , as it always is in my garden, and it started to fall over, and i had to put a 50 pound bag of sand, on the base to keep it in place.   The material does not seem that strong, i don't think it will last long, out side in the hot sun , and the winter.   !    No where near as good as my last offset umbrella and base, but i did not buy that from you.   Only time will tell .        J.J.       San Diego
