I got a BBS with a Gillette Fusion today
I had some old cartridges laying around from my pre-DE days. My stuff is packed for a vacation and I needed something to shave with. I picked it up and used it, and I got an effortless BBS. Honestly, it was one of the closest shaves of my life. However, I am not going to go back to carts for two very important reasons:
1. The carts cost a lot of money!!! and
2. The carts cost way too much money!!!
Also, I think the reason I got a good shave with it relate to the facts that I was using Mike's instead of canned goo, I did a three-pass technique which I developed with a DE to begin with, and I had two days of growth (which was the only way I could get a decent shave back when I used carts). I have a feeling that for daily use, it would not work as well as my DE does.
