One has to like purple, but my brother does. (I bought this for him, after watching the excellent YouTube review by user X4ACTO.

+ Comfy strap shape
+ Comfy case and strap, due to  textured surface, which allows the wrist to breathe
+ Stopwatch progress bar graphs on home screen remind the user that s/he has a stopwatch running. I don't know HOW many times I forgot this on other digital watches.
+ Color is quite different from the norm. Easy to see, esp. with the backlight actuated.
+ Well-sealed buttons. While all other G-Shock buttons remain waterproof, these can be pressed while wet, I don't think a lot of us mess around a lot in mud, but one other thing it is useful for is being baby vomit resistant. ;)

- Kind of a high price, just for purple color scheme and mud-resistant buttons. Consider the regular 9000 series Mudman if you're not big on this color.

I will update this review as time goes on, with any surprises, good or bad. My brother is not a collector like me, He'll wear it every day, so it will get a work-out!
