I never had a sensor, I remember my Dad using one. When I started to shave 15 years ago I got a Mach 3 and used that exclusively until about a year or two ago when the handle broke. After that I was given a fusion mail sample with one blade and started using the fusion. Well I quickly found that I did not like the fusion as much as the Mach 3 because of price which led me to look into alternatives... Now that I have used DE I never want to go back!
4 Fusion blades are a crazy price! Around 15.00 for 4
In Bestshave you can get:-
100 Rapira blades 4.79
A Yuma razor 1.99
Horse shaving brush 2.13
Derby Soap Tub + 5 Derby Blades 2.99
Total 11.90
The rest is postage! Give or take a buck! I know what I'd rather shave with!
