The product I got doesn't look like stainless steel but more like a chrome-like metal product. Definitely not the refined product you see in the product page pictures. It opens beer bottles well. It also opens jars, but you have to be careful not to put your finger under the black slider. I have tried it with cans, and I find it unnecessary unless you have some problem with your fingers or not enough strength. In all honesty, it takes me less effort open a jar or a can with my own hands. I needed it mostly for beer can opener than anything but the price is low so the other features might come handy in the future.
