I KNOW this didn't cost much & u get what u pay for but I was using this umbrella for the first time in a windy storm the other day. It worked very well when facing into the wind of Id say was 20 mph maybe gusting to 25 occasionally. HOWEVER, once leaving the store, the minute the wind hit the umbrella, before I even had a chance to flip it behind me, the whole spine had turned inside out & broken one of the arms.
I took it down immediately, almost all in one motion of it turning inside out but it only took that second & it was broken. It will still operate but theres no way to chance using it because the broken spine could split the material at any moment. It looked good & might work on a still day w no wind.
