Master Jar & Bottle Opener, Adjustable Multifunctional Stainless Steel Can Opener Jar Lid Gripper, Manual, Kitchen Accessories

Works well on most jars
Effective when it will fit the jar – teeth have to line up with jar lid. Also requires a certain amount of grip strength to operate. But overall it works and I am happy with it.

This is a waste of metal and not worthy of anyone’s attention
This device in photographs and in general concept is convincing: finally a tool which allows a person to solidly grip a lid and twist it off. This year I purchased this and a different kind of tool and both failed miserably to do what was expected. I should have paid greater attention to the size and some of the details and maybe, just maybe, I wouldn’t have wasted my money on this.The jar grip. This is a toothed rim which may work to bite into a plastic jar lid of a certain size. I am not completely sure what it is meant to work with. All I know is that it won’t grip any lid I work with. What I thought I saw was a grip made of rubber of great enough width that when compressed against a circular lid on both sides would hang on while the lid was loosened. It is not there. The grip is useless.The lock. This is handle that looks like it locks down and keeps the grip tight while you then move the overall device anti-clockwise (or to the left). This doesn’t lock anything. It engages with a toothed surface but does not stay engaged. You can’t keep pushing this down to keep the grip while also attempting to rotate the entire device. Instead I was expecting more of a vice-grip sort of approach that allows the grip to be tightened and locked in place. That is what I thought I saw in the pictures. It is not so in reality.The length. I really wanted this for lids which have a diameter of more than a few inches. They are tough to loosen. You need the length to be at least twice the expected maximum jar diameter to get the leverage needed to twist off the lid. The key element to making this dislodge difficult seals is the leverage. This device is too small to accomodate anything but the smallest lids.In short, this device was meant to look like something that should work and fails miserably.

This thing is a miracle!
I’ve looked for a lot of products under the umbrella of “arthritis” or “seniors” or “weak hands” and I’ve seen a lot of products with 3 or 5 holes for specific shapes of jars, with a single-hinge kind of design, and I knew that was no good for longevity.This thing is PERFECT for my needs. It’s adjustable to all kinds of lid sizes, thanks to the grooves cut on the inside of the long sides, and is completely battery-and-electricity-and-smartphone-app free! There’s only two moving parts, it doesn’t need dishwashing (cuz the outside of your jar should be clean when you go to open it anyway), it’s completely emergency-proof!That said, there is a bit of a learning curve. I cut horizontal lines into the sides of the plastic jar lid I used this on the first time or two! Those jaws mean business!I learned I have to place the tool down onto the jar “upside down” so that smooth parts of the tool are on top, with the handle piece to my left. I then have to move the sliding piece into place on the opposite side of the jar lid, then squeeze down the small angled piece with my left hand, which locks the little metal tooth into the grooves on the inside of the handle, so the tool no longer adjusts its diameter around the jar lid. Finally, while squeezing, I turn the handle it towards my body (and say out loud, “righty tighty, lefty loosey”), while holding the jar steady with my right hand. That has given me the most consistent success.

Opens Bottles and Jars
Great for arthritic fingers

I have had multiple stroke s. My right side has lost both strength and grip force. I have 3 other bottle opener’s. Each only works on one bottle type. I brought this on looks only. The design and length of handle makes strength and grip a problem of the past.. the only issue that I have is on some plastic bottle top that are supper tight. It is necessary to get the teeth to grip the centre of the cap lid. The ability of this opener is such that if it is not on centre line it will rip the lid or cap apart. Other wise it does a brilliant job. I can not be more happy with this product.

Not a well-built item haver real problem trying to use it as described. I have given up using it as it does not work.
