I thought these would be good for adapter issues, they didn't thread to a single one of my camera or telescope threads. When you screw them together, they lock up very easy, and they are very thin. I did not find them useful in any situation I tried them in.

These are easy to use and work great, you can combine multiple rings to get from 1 size lens to just about any other lens size. I didn't have any problems with them being stuck together or anything (maybe some others forgot lefty loosey-righty tighty, idk lol)...anyway, i use these rings so i can swap my filters from lens to lens and also to make a macro/wide angle lens fit on teh end of my lenses, so I can use the macro on a 50mm or a 55-250mm zoom...pretty cool stuff :)

Looks and feels like a good product. Definitely good to have on hand for when you need it.

Rings come in handy when adapting my lens filters to other size lenses. Rings seem nice and sturdy. I just wish they came with some sort of pouch or case to carry them all in.

The bottom ring’s thread of one of the stacks seemed stripped, so for me the ring just spins in place instead of tightening. It’s really not a big deal to me as it still holds well, but it’s worth mentioning, as this might untighten on someone and break their filter.Other than that it’s a great product and I’ll find myself using it for the rest of my career.

Very good quality aluminum adapters as k&f is known for. This one is no exemption that why I always trust these products from them.
