They're rings with threads....they're threaded rings. They work, just don't jam them too tight.

good quality aluminium.bought for polar filter, filter bracket.rings dont get stuck on the lens or in eachother, even when turning the polar filter.

These were a great price, and they do work, but the build quality could be better. The metal is a little thin and more difficult to screw on the filter I’ve found, than other brands. I tried the Neewer filter adapters first which feel more rugged, but are more expensive. At the end of the day I didn’t want you o spend a fiver I didn’t have to, but if quality is a concern bear in mind thinner means slightly more tricky to screw in.

Works great. When installing you must be careful as these have precise threads. A good practice is to mount the adapter using an unscrewing motion first to align the threads. This makes installing much easier. Also don't crank these down super tight! You only need to lightly snug these down to your lense and filter.

these are a must for any photographer, i only needed a few of these but for the price i just bought a full set as i know i will need the others one day. so far no issues, they do what they were made to do!

These arrived in good condition, in 4 stacks to nest/save space. None were overtightened, it felt like some care had gone into this, with each ring screwed in enough to keep them together without risking binding.If I were to be picky, each of the two sets (up/down) came in a very cheap plastic bag and my bags had cuts in them, so not really suitable for continued storage. But I guess storage of filters or these rings is a personal thing, so not really worth the manufacturer including a nice pouch.

Not toting around several filters; or spending the money on them when you can use these is great. I find myself accidentally touching the filter glass more often using these during the exchange so make sure you have ample lens cleaner on hand.

Not only can you stack these rings to adapt almost any lens to almost any filter, they also make a handy build-it-yourself lens hood.

The rings are exactly what I expected.They are made of a solid material.They have a fine finish.They work perfectly and I will be enjoying its functionality.
