What the smallest lid this will work on? I have some that are 7/8".

I do think that the smallest should work for 7/8. If you buy a gallon of water that cap opens with the 2nd spot. As a bonus with this tool you can open pull top food cans. On the big end you have a flat piece that pulls up the ring on cans. Then hold tool straight up by the handles and put thick piece on ring and brace the ring pull up to edge of can top and pull back.. I have Arthritis and this is the best product I have found by far and the price is great also.

Will this help open a wide mouth pickle jar?

It well but not with the round part. On the top is a hook and you pop it on and lift. Like an old bottle opener. Once popped it twist’s right off.

will this fit a 4 inch lid?

I don’t believe it will as the largest opener is barely 3 inches and won’t stretch to 4.

How is it a CAN opener, pls?

The product description states "can also be used to open the ring pull cans" so I suppose it can help to open cans that have a ring pull on them, but I have not tried this function. It works pretty well to open jars with twist off lids though.

Brilliant!

This thing is so useful! I've never been able to open jars properly and since losing even more strength due to health issues I was finding ot very difficult to make food without constantly asking for help. With this gadget I can open almost every jar I come across.

Useless for ring pull cans.

I bought this to assist my wife opening ring pull cans of dog food because the recent batch of cans were difficult to open by hand. I tried to open three cans with this new opener only to break off the ring pulls. I then tried it on two easy to open cans of tomatoes with the same result.I have not tried the other functions but the way that it shows to open the smallest bottle top is employing the principle of a class three lever and as any child who has studied physics to first year secondary school (year 7 I think) would tell you, this offers a negative mechanical advantage, in other words you would be better off just using your hand.
