The ordering/cancellation process failed. I ordered a heavy duty, green umbrella.  The order processed as tan.  When we cancelled the tan, the green was offered only at a higher price. Bait and switch! Received both tan & green so had to return the tan, we were charged shipping on the return. Quality of the green unit is marginal, the locking system (two different types of levers is under designed and too weak to allow the unit to hold itself in a tilted position.  It woes ok as long as the unit is completely horizontal.
Refund was handled promptly, only positive from this transaction.
