Jar Opener for Under the Kitchen Cabinet Counter Bag Bottle Arthritis Screw Cap

The item we received does not even resemble the jar opener shown. It is a cheap version with the smallest metal teeth that will not even open a water bottle. It has a glued backing to place onto underside of your cabinet, so we cannot even remove it to return. Incredibly disappointed in this product.My Email is Franw4032@ Gmail.com... please advise me as what I can do ...
