Catch cans - anyone use these?

I’ve never seen this type before. To anyone who does use them, do they work okay?

I don’t use that one. Depends what you are using it for.
I like a clear(ish) container so it is easy to see what is in it. In some applications the catch can needs venting.

Sorry I am not able to upload pics correctly ATM.
On an LO206 I use this:

Very simikar to this:

Price is good too:

Maybe not cool looking but cheap enough and easy enough to carry spares and make it a go to option.

Yeah, I’ve used those. Just ran across these & wanted to see if anyone has tried them out.
