I am worried about some people's complaints about the rings not releasing and getting stuck to your equipment. What should I do if that happens?

I have not used them to extensively but the three or four times I have, there was not even a hint of them sticking to the equipment. I do not think it is something to worry about. This is the first time I have heard of such a thing.JC

Hi Brian, I have not yet encountered such problem with Polaroid extension tubes. It is made up of good material and I used all three attached to my camera with one of my heaviest lens. Its bit cranky while releasing but it's just a matter of practice.

I don't have a direct answer to your question but I can tell you that I have taken these on and off hundreds of times with no issues.

Mine almost got stuck. The release lever is a bit flimsy but with care, it works. Rather stiff though...

Perhaps contacting the manufacturers would help. Have had no problem with mine so far.

No. Notify the company & they will send you one that has been loosened. They have to know that this is a serious problem, not a one-off.

Sorry but I never had that kind of problem. Maybe if you vigorously wiggle the red release mechanism? It does stick sometimes. Good luck.

Oh, sorry I misunderstood. My ring moves very freely. Your projector must be defective.

The rings don't come off of the bar. But they don't seem to get in the way when using just the bar.

I was about to return mine after pulling and twisting like crazy without being able to unlock it. I gave the ring one last herculean twist/pull and it came undone. It seems that the mechanism that keeps it locked is a bit too tight. Once you get it going, it works great! Good luck!

If the release mechanism doesn't work properly and it is stuck, be VERY careful. I damaged two lenses with a cheap adapter that was not machined properly. Take it to a pro if you are not good at working on things.

The ring is supposed to remain stationary. Only the black metal base should move. I also double check my depth or radius with a measuring tape.

I bought one that was a little chipped on the bottom and the ring didn't come up either (I pulled hard!). I returned it/replaced it--first for the chip, and because I couldn't pull it up. My replacement came up with little effort. I wonder if some are defective. But yes, you are just supposed to pull.

Mine is perfectrly 'tightened', focus ring fits perfectly and it runs so smooth! Only 'problem' that I notice is the 'noise' during IS activation. But, it turned out that Hybrid IS is such noisy. If there are problems, maybe you should thing about returnig product?

The two previous answers cover it ...I had a heck of a time with middle ring...my brother helped me..also make sure the support at the base is tight

I have high rings as well and have had no problem. I highly doubt that the height of your rings is the problem.

If you are talking about the adapter ring, they can be difficult. They come off counterclockwise. You can try a plastic jar opener grip and try to grip evenly around the perimeter, otherwise you will just pinch it and make it more difficult to remove. Good Luck

Mine are loose, too, which creates an unacceptable instability. For such a highly-rated product that otherwise seems pretty solid, this loose connection is really troublesome and unacceptable. They should offer alternative bolts and/or washers to ensure a more snug and professional fit. After all, this is a component that bears weight on each of the different exercises possible.

I didn't have any trouble. All the hooks were accounted for. Like you said, you might have gotten a defect, and maybe you can exchange it.

You should ask your gym. They don't damage equipment, but you should ask the establishment in case there is a liability issue or something.
