I'm a little disappointed in this product.  I guess "full size" is a matter of opinion.  I bought it to replace an older Totes compact but this one doesn't open as big as the old one.  The literature that came with it says "43 in." but the sticker on the other side says 38" as reported here.  However, it is a bit clumsy to close, and the handle that houses the ends of the umbrella when it is closed is not round but oval, making it a bit difficult to position the tines into the handle upon closure.  It's "O-Kay", but at better than $22 I expected more.
