KUHN RIKONStrain-Free Gripper Opener for Jars and Bottles, 8.75 x 4.25 x 2 inches, Red and Silver

I purchased this opener for my mom who has trouble opening large jars. This produce far exceeded my expectations. Easy to tighten over jars. Not necessary to over tighten. Teeth on the 3 contact points do mark the sides of the lids, but these are jars of tomato sauce, beets, honey. Not looking to save them. The handle is what makes the difference making it easy to turn. My mom is able to open and close Large jars down to water bottle lid size. I'm thinking of buying one for myself.

It's an interesting design. It does work fine. However, for many jars I had to get someone else to hold the jar while I was turning the tool! It is really hard to do it alone unless the cap is not too tight. One hand on the jar and one hand on the unit just does not work most of the time. So, if you have arthritis and no one to help, this is not for you. Even without arthritis, if you live alone, this is not for you...

I bought this item for my wife who has arthritis. It's a godsend for her. She was unable to open most jars and I'm not talking about brand new jars that haven't been opened yet. I'm talking about a jar that has already been opened. This items attaches very easily with a few turns of a handle and then the leverage comes into play. She has virtually no problem opening any jars anymore. One of the nice things there are no batteries and there really is nothing that can break on it. Very good item to buy for those who have any physically limiting abilities. Also I use it myself to open brand new factory sealed jars that are really hard to open !!!!

A clever positive lid-clamp design. The first one we received was jaw position* flawed; a brief text to the manufacturer resulted in a replacement unit being mailed out. No further operating abnormalities have been noted; time will tell if a 5th star is warranted. We're good.* So the three jaws don't line up; can it be d-i-y fixed? Well, yes, if one has curiosity, patience, a screw extractor 'bit' set, and a go REAL slow cordless screwdriver. We're good, twice.

It works well but difficult to use. I really need to make sure that the teeth are on the lid properly. There are times when I had to reset the grip a few times. Once the grip is on properly, it was easy to open the jar. The opener looks very sturdy.
