"Ordered on April 21st, finally arrived May 20th - too late for the trip it was intended for. This is only after emails asking where it was, and opening an issue with PayPal. They made claims that the time for an order to be processed was on their web site, but it is not. Bottom line - allow lots and lots of time for your order to arrive.

Product itself is fairly well made, but will only work with some types of doorknobs. In addition, the door must open into the room for it to work."
