Bests & Worsts Reviews from Amazon

The locking mechanism on stem of handle consists of a tiny plastic tab. If you don't tighten this mechanism up enough, air will escape and it won't do the job. If you tighten it up too much, the tiny plastic tab will break... rendering this product useless. The latter happened to me. Received this product a week ago, and it's worthless after only 2 uses. Don't even know if it's worth the effort to try to return this product since I already tossed the packaging in the garbage.
