I first became aware of the "Tes You Can" can opener while serving at a church in FL in the kitchen this past Winter. it was wonderful.  When I left in March one of the ladies gave me one as a gift.  I didn't get a chance to use it until I got to VT to serve in a camp kitchen in May.  When i tried it the one I had been given made a screeching sound and would not open the can.  When I contacted Kitchen Mama and told them about what was happening and that it was a gift (so I did not have a receipt) they got back with me the very next day.  They suggested I try some things but if that didn't work I was to take a video and send it to them.  They immediately shipped me out another one which works beautifully.  I have never been so impressed with the quality of service and the friendly emails and the quick and competent service.  I can't thank you enough Kitchen Mama.  I love the can opener!!!
