Query: A Great Concept that Fails in Execution

I had a similar experience to most of the other reviewers. I had great hopes of this product -- expected to enjoy low fat cookery without the mass-produced flavor of most commercial cooking sprays. I had visions of chicken enlivened with pecan oil; salmon fired up with hot sesame oil; fresh tomato pasta sauce with just a hint of extra, extra virgin olive oil. Well you get the picture.However, I was doomed to disappointment. I filled it the first time with best-quality olive oil. The first spray worked just fine. And the second. But come to use it the third time and the plastic "guts" were broken -- irretrievably. A costly kitchen gizmo obliterated by a 5-cent part.I'd love to see this product relaunched with interior workings to match its exterior. Until then, guess I'll just have to keep using Pam and dreaming of something better.Sigh...
