Love this umbrella!  It's very easy to put together, literally one part to click in.  You do need to buy a base for it.  I bought a 48 lb granite base at another retailer and it holds it up without having to have it in a table.  It extends easily and you when you crank it past full open it tilts.  It's very well made, the umbrella material is very sturdy and solid.  It has a vent to help prevent (no pun lol) from flying away.  SO happy I got this!
