You know I've been pretty happy with Toro stuff in general but I've gone through 3 of these now in 4 years and that's ridiculous. The first year we had a brief and unexpected freeze before I got the lines blown out so I took the blame for that one even though it wasn't a hard freeze and was brief. So, I tried it again but the 2nd time I got the lines blown out on schedule and spring 2011 the PVB was toast again blowing water out everywhere. So, this past winter, I not only blew it out, I unhooked it and brought it in the garage. Just hooked it up this week and this one is toast too. Going back to heavy duty metal that lasted me 15 years even surviving unexpected freezes. This thing is a cheap plastic housing and apparently has some pretty cheap internals as well.
This product is made of hardened plastic and when installed and maintained properly should last a long time. This vacuum breaker was installed for an outdoor backyard sprinkler system. In Massachusetts, a back flow valve is mandatory to prevent any outside water from entering your homes potable water system.
We definitely needed to purchase this product because the one on our sprinkler system was leaking profusely. After pricing the product on the internet, I found that Home Depot had the best price. As to its performance, I couldn't say. It's exactly like the one I replaced, and that one lasted several years. I'm hoping this one will do the same.

The only thing wrong with the old one, which was exactly like the new one, was the plastic nut holding one of the unions. I should have been able to buy just that part, or any other part. Not good that you have to buy the whole vacuum breaker if one part breaks.
