Query: WHAT A JOKE

What a joke this thing is....I wonder how products like this even make it out of the test kitchens/laboratories. I mean seriously, if all it takes to invent a product is a good pitch man then I'm in the wrong business. I'm going to turn into an inventor.I will not waste any words or time on this piece of trash.We bought into the pitch man's advertisement and picked this thing up...It NEVER WORKED RIGHT. NOT ONCE.You put it on the can, start it and then it would stop in the middle of the can. The reset button didn't work the opener became stuck on the can and then we had the pleasure of PRYING THE THING OFF OF THE CAN which took a lot of work. We tried replacing batteries...nope. NOTHING.ZERO STARS.WOULD NEVER RECOMMEND EVER EVER EVER!
