Extender lock doesn't work
Poor quality materials overall, and to top it off, the locking mechanism for the telescoping extension doesn't hold - You can just push the door open with a little extra force

    Put this on my sliding patio door and can still open the door. Worthless.

    It is a simple, functional solution to increase security of your sliding door. The install was easy and quick. Good solution.

    Excellent design and great value for the money. Instructions are not so good but very nice unit.

    This item is not a quality item. It feels like a 12oz coke can; that could be crushed easily. At 28 dollars your better off spending a few bucks on a piece of straight wood then this thing. The store clerk who recommended it should be fired.

    This was very easy to assemble and works as it should. No complaints so far.

    It takes some skill to drill the holes precisely into the patio door frame, so a friend who works in construction did it for me. The bar seems a bit flimsy but seems to be doing its job.

    While the crossbar/lock I purchased is an excellent item, it is too long for my sliding deck door. Therefore I will be returning it.
