I'm not sure how long they have been around for (the last time I searched for NT30 a month or so ago they never came up) but I've never seen or heard of them.
I've just noticed tonight on a search of AliExpress for NT30 that they now have NT30 spring collets, similar to R8 collets that have been around for years.

Has anyone have experience with them, Pipeclay, RayG maybe? as they the same mill and is up on most things.

Wondering if there any better than ER collets as there around the same price, but come apart every time you change tools which would be a pain.
Maybe I'm out of touch with what's around today. Other than the past 12 months I haven't been machining for 5 or so years years with life comiments.

I have around 40 ER series collet chuck's of all different sizes so don't really need anymore, but am curious to try one.
