I bought two of them but i have not opened them yet.
but for the price i paid im sure they will be just fine to sit under 
and get drunk.
if you are looking for an umbrella for a 3 million dollar mansion
then get up off your wallet and spend a few hundred dollars and get a premium umbrella , they probably come with a nice stand so you wont
have to freak about a base stand for it.
Dont expect a diamond for a zercon  price, only try to get away with that 
when your buying a wedding ring . 
umbrellas protect you from harmful uv rays.
enjoy your out door living and bottoms up!
Buck.
