Only have used it a few times.  It is much bigger than I expected, and much thicker too.

I wanted something I could just keep in my briefcase all the time, but this is too big and bulky.  But is seems of good quality and durable.

I will have to get something smaller.  Saw something on Hammacher Schelmer.

Wanted a good quality umbrella, not a flimsy--this does it, only complaint is size not meeting expectation--but that's my own expectation, so no reflection on the product.
