This purchase goes into my top 5 all time best purchases ever!  Sturdy, compact, made well, best of all 55 UPF Sun Protection, and waterproof.  I keep it in my car for use at the beach.  Whenever friends want to sit in the sun, I can always sit under shade with this UF umbrella.  Well worth the price to buy this excellent quality that will last longer than the cheap brands that don't provide high UPF ratings.  The endorsements by major skin cancer research centers speaks clearly for this product as well.
