It looks like UM changed the faceplate to being flatter which is a good thing. I owned the original MEST MKII and the faceplate was more contoured which resulted in the metal “hats” falling off since they are just glued on. The contoured faceplate led to the hats not being glued on as well. Congrats on your purchase!
Thanks!
I can't speak to degree in which the original MEST MKII contours, but this one does have some. Like you said, it looks like the metal parts are solidly glued. Nonetheless, I'll keep an eye on them.
