With a fusion I get 3 – 4 shaves
With a mach 3, I get 5 – 7 shaves
With a DE, I get 3 shaves.
So with the DE I need to change the blades more often. However, I prefer the feel of the post-shave results (so does MrsG) and it’s cheaper:
Fusion = £2.12 per blade (£16.99 for 8 from Boots[/url])
Mach3 = £1.43 per blade (£11.46 for 8 from Boots[/url])
DE = £0.16 per blade (£0.81 for 5 from shaving.ie)
Therefore, the fusion will cost me £15 a month, the mach3 £6.13 a month and the DE £1.60 a month – approx.
The price may go up a bit as I try different DE blades, but should still fall short of the Mach3.
