umeniceUPF 50+ UV Protection Travel Umbrella Ultra Light Weight

I have recently purchased this umbrella to block the sun on my way to work. I can see the following:9/10 for sun blocking as advertised.6/10 for windy weather. It was not very sturdy against wind.9/10 opening/closing mechanism. I had no problems regarding that.10/10 in size as it was very suitable to me.I have given it 9 as I did not try it in 40+ degrees sun yet. I suggest you use it during the summer or at the beach.
