These do what I need them to do. As commented by some others, these are tight on the threads, particularly the thicker spacers. I did find, however, that putting them into hot water for a couple of minutes made it much easier to fit them.

Quite poor. The inner aperture wouldn't go over a T2 thread unless forced. Good range of thickness' is about the best I can do on these.

They seem to be of setting size. Do not 'slip over' T2. It's been an absolute waste. I broke a ring while trying to insert over a t2 thread, so guess can't return as well.
Solves a problem, but not ideal

The tolerances on these items are very good meaning I can sort the spacing out, but the ones I received far from "slip" over T2 threads - requires a fair bit of effort and very tricky then to remove later. 2/5
A Must Have Accessory For Astrophotography

After years of having T-thread adapters and filters and nosepieces and spacers locking together and then defying any attempt to open them again, and after trying everything from milk bottle rings to PTFE tape to stop them sticking, these Delrin Rings from Baader offer one of those simple but beautifully effective solutions that make all the difference.
Not only do they help prevent threads locking tightly together, but they can also serve as great 1mm spacers, essential when trying to achieve correct spacing between cameras and reducers.
The spacers themselves are well made from neatly cut Delrin, and they press onto the male T2-threads quite easily, without distorting.
I have now added spacers to every T-thread accessory I have, they work so well they should probably be standard issue, definitely a must have item for anyone using T-Thread fittings. I only wish I'd found them years ago!
