I work in the lab and need to open urine cups. The lids are plastic and not tight. Will this jar opener to be too strong for light tension?

I really don't know...I don't think it clamps on that tight...really just holds jar firmly in place while the top turns and opens...

Wish I had a small plastic bottle and I would try it. I'm sorry, I do not know if it would work for you.

ot recommended for plastic .I tried it on plastic jar .the opener crushed the jar and ended up breaking the opener jaw.:)

The unit is pretty heavy for a jar that small. I think you would have trouble with the weight tipping them over and potentially crushing the tops.

Mine stayed closed so well I had to loosen it a bit so I could flip it open easier. You should have no problems. (:

I have arthritis in my wrist and can use it with no difficulty. If you can hold the jar with one hand & push the handle of the opener with the heel of your other hand, it shouldn't have to involve your thumb on that hand. My concern would be the thumb of the hand with which you are holding the jar. We find it to be a very helpful tool.

I have to use a rubber jar opener to get a tight fit. I've also had to replace that lid a couple times. The rubber gasket gets loose. Good luck!

Bummer! Mine just opened right up, but when I close it, I have to twist firmly to get it to "click" all the way closed. I have a trick I use when I can't get a jar open-maybe it will work for this: hold the container upside down, and smack it sharply on the counter top. You may have to do it a couple of times, but it always works on jars! Just make sure you keep it level, so you don't break the container...good luck & sorry I couldn't help more...

At first, I didn't think so, so I tried it on an old UNSEALED, but partly rusted shut, vacuum lid, and it will fit under it and lift it. I didn't have a sealed jar to try it on to see if it would bend it.

It pulls off and you just press another on. I use one of those rubber grips used for opening jars. It's not been difficult.

No, its a total pain in the ass to open a can, that is for sure. Ive tried openers, screwdrivers, small chisels, etc. What happens is the thin metal in the lid just bends up all the way around the can as you pry away and the seal wont budge. I use a hammer and a thin screwdriver in between the seal, the worst part is when you want to put the lid on to save the remaining gel everything is bent all to hell so it cant be resealed effectively.

You just set it on top of the jar and it works hands off. However I have had it slip when the jar is wide then narrows quickly at the lid. Overall, it does an amazing job of opening really stuck lids.

I haven't had that problem yet, but ours has already cracked at the top so we decided to quit using it. Half the time it was difficult to open certain jars especially plastic lids. I feel its not worth the money and I advise you to return it for a refund if you can.

I am not sure about that, so far mine is still very good at opening all types of cans, although I assume eventually it will become dull and therefore harder to open the lids.

Yes, it is very good to open jelly, pickles, smal and larger jars. I cannot live without it. One caution: Do not use on ver soft sided containers as you may have un suspected consequence. Diane

Sounds like what you are trying to lift open is to light, I used them on a heavy door and they worked fine , the weight of the door pushed them closed , now the spring should work in your hands if you force it to close

I have not had trouble. Others have said press real hard on lid, maybe with foot pressure and it should open

If you aren't too harsh with it, the Ball or other canning jar lids open easily and are not damaged. As with anything, if you are rough with it, then it can be damaged.

I have successfully opened one, but am not sure if it was luck or if using it lightly at a couple of different places on the lid kept it from bending. I have not tried it since. Sorry I can't be more help.

I don't know how difficult it is for you, but I think the plastic lid is easy to lift. And I've had many different plastic containers where it was very hard to open and close. I am very happy with this product. But where you lift the lid, the piece is small, so keep that in mind.
