Query: Waste of time and money!

I've switched from using BIC throw away razors to the 8150XL and now it takes me three times longer to get rid of all the stubble. Even after wasting all that time I still find it necessary to go over my face with a throw away razor. (And, I have lite facial hair; I pity the guy that must use this on anything heavier).I'll be using it only when I absolutely need to do a dry shave.Oh, on the positive side, the ergonomic design is cute, the LEDs are bright and cheerful, and the stand holds the shaver well.
