I returned several all-plastic sprayers to Lowes and Home Depot before ordering this one from Amazon.  I've got to say that I have yet to experience the problems I had with those sprayers.  My only complaints are similar to other reviews: the lack of spray pattern options and the fact that it tips over when set on a flat surface.  The latter drawback and make it more difficult to get set up, but this minor inconvenience is much better than multiple trips to the hardware store to return defective items.
