I ordered a black Totes auto open/close umbrella from Revain (not a third party) and it works very well. The metal ribs are stronger than a regular umbrella, but my hinges broke after a few months of casual use, and the auto open and close feature is very handy. The umbrella fits easily in my laptop bag, but is a bit heavier than a standard umbrella. The umbrella is covered by the Totes guarantee, but I have to pay the cost of shipping the umbrella to Totes. As of this writing, the USPS flat rate envelope costs $7.35, so that would be a reasonable option.
