Review on AMMSUN 7.5Ft Commercial Grade Beach Umbrella: Sturdy Ash Wood Pole & UV 50+ Protection For High Wind Conditions by Justin Anderson

We spend a lot of time at/in our pool in the summer. Most pool umbrellas are terrible at actually blocking sunlight. I'm sure there is a reason for that that I am unaware of, but after six or eight hours, I like to be able to sit there and not get fried. I went to the beach a year ago after not having been in several years and the dude there rented us what appeared to be a canvas umbrella (looked just like this one) - that thing let absolutely NO light through. If this was like that, I would have given it five stars. This is, however, the next best thing. It definitely blocks more light than our other umbrellas (I did buy another one a few weeks ago). I think it blocks 95% of sun, so all day under it in the middle of the summer and you will get some sun, but not be too toasted (still suggest some sunscreen). I do wish it was larger (our other umbrellas were 11'), but winds that would have killed our other umbrellas haven't bothered this one.
