Very happy with the improvement in this can opener ! ! ! I have purchased this product by another producer and really liked it. It was lighter and tear drop shaped. And more Expensive… I was opening a can one day and it quits working while attached to the can ! ! Could not get to the button to use to release the can as it was placed under the product and between the can and opener. Ended up having to empty the can as best I could and chucked opener attached to can into garbage. I had been using it for several years so felt like it had paid for itself.. The hunt begins ….Found several approximately the same price THAN found this set of two (2) for less than I paid for the single one. I did not want to be caught without an opener again so I purchased some of the army can openers to give for in the glove box for family , an old fashioned manual can opener and these…I was impressed they had Manual Release Button on the side, NOT hidden away and unusable. These are great if you have arthritic hands , shoulder problems etc….BE AWARE they will not work on odd shaped cans or bottoms of cans. Having two is great in case one stops working or if company comes and both want to open cans at the same time like that will ever happen hahaha!!! But if you camp etc the second will be ready as soon you install 2 AA batteries.. This improvement made this a Great product in my book….
