Query: Not worth the absurd cost- very flimsy

I got just over one hour of use out of this valve before it simply stopped working. There is nothing visibly wrong with it, and no clear way to fix it. Now, when I depress the cheapo pressed-sheetmetal lever the gas supply shuts off and the flame extinguishes. I recommend the much simpler and less expensive dial control valves seen on the older flaming wands. They work for years, are less fragile, and very easy to control. They also cost about $6 at the store.
