Well maybe not forever, but definitely a long time. I've bought plastic sprayers in the past and always hated them because they leak or don't hold up well. This is very well made and also works very well. I need to play with the sprayer a little bit, it constantly sprayed when I pumped it up the first time, so I'm sure there is something that I need to adjust that I just didn't do. Otherwise, very happy with the product & even my Dad liked it and he doesn't like anything.
