I think they are worth the money, there are many options.
The pink blade (can't remember the name right off hand) is awesome for On-the-go girls!
If you need a really quick shave, you don't need to use shave cream with this razor. (I don't suggest this all of the time bc it can cause skin damage) however, it's very nice for quick fixes/vacation/lazy days!
You can mix&match all the blades/ razors
