This little can opener is awesome. The snap lock design is what makes it so awesome.  Once you get in in position and lock it in place, there's no slipping off until you release it yourself.  The shipping took quite a while, but I knew that before I ordered it and was okay with the wait.  It was well worth it!  I just replaced our old manual with this one without mentioning to my husband.  We were sitting at the dinner table and he said, where did you get that little can opener, it works great!!!  I told him, WAYFAIR!!!!!! Small purchase, big results!!! Thank you Wayfair!!!!
