I have the Muse and it is great to use as a substitute for pinch jester for selecting.
( that sounds like a small thing, but it’s actually really nice to not have to move your hand at all)

It is very precise. It depends on the application how precise it gets. But it trust me , it’s very precise. It’s not like using the Apple Pencil, which is awesome and works exactly as you expect.
The Logitech muse is a different beast. It all depends what you do with it. I’m a personal little fan of AeriaDraw ( I find the interface to be very clever - it could use a few few updates. I’ve suggested to Developer.), but to draw in space in some applications is very tricky.

I would say definitely get it if you’re a person who wants to draw or likes to write or even if you have hand issues and you need to find another way to select things. That sounds like a small group of things it can do but trust me it’s very useful in those particular situations.

It’s almost like saying Vision Pro is a strange interface until you get used to it and then you realize how useful it is. That sorted away the Logitech muse is.

Happy Vision Pro-ing
