You get what ya pay for.
I received the green umbrella saturday, attached the metal pole 
 & placed it in (my) base. It opened smoothly with the hand crank that seems sturdy. The top of the umbrella IS plastic which worried me a little....will That last?
The material is just  " alright".
I notice today-TWO days later, that the metal "arm" ripped thru the little pocket that keeps it on.
I can probably sew it closed pretty easily, but didn't expect to be repairing it after just 2 days.
