When Gillette introduced the Fusion I swore I would not be among those buying it.
Anyway, I received some gift vouchers for xmas and thought “Why the hell not”
Man, I tell you, I have never had a better or more closer shave in my life.
The little teensy blade for the awkward bits under your conk is great.
Yes indeedy, colour me converted 
I admit, I’ve always been a double blade guy. But, like you, I got some fancy multi-multi blade things from my M-i-L over the holidays. Damn if it doesn’t get the job done better.
I tried the triple blade thing for a while. It was my belief that it did give me a smoother shave - but the ROI wasn’t there for me, so I went back to double blades.
Triple blade…Pshaw!!
Fusion has 5 plus a diddy one at the rear of main slicer
…and I wait with bated breath for the 10 bladed monster
I still haven’t tried the Fusion. I went electric last year, but I still use a straight razor (a Mach 3) for the finishing touches that electric just can’t deal with. I’ve yet to try the Fusion precisely because the price of blades has increased absurdly in the last couple of years. I used to be able to buy a 4-pack of Mach 3 blades for $7. Now I can’t get 'em for less than $10. Why? Hell if I know, but I blame it on the Gilette Cartel.
More’s the pity I suppose because they really do offer the best, smoothest and closest shave. I’ve tried the others. Every damn last one of them stink by comparison. I have sensitive skin, so the difference is painfully apparent. I need to buy some new blades now, so maybe I’ll consider a Fusion just for the sake of experimentation. I like the single blade on the back. My electric has a flip-up trimmer but it’s only good for trimming the bushiness of sideburns, not getting a smooth shave when you’re done doing that.
I’m still using my Sensor. I’m holding out for the Gilette Infinishave™ (with an infinite number of blades).
I found the fusions head to big to allow for shaving under my nose.
Obligatory Onion link [warning: language] – We’re doing 5 blades!

I’ve tried it. Costco sent out a free Fusion razor to customers. The idea being, of course, that you’ll try it, like it enough to keep using it, and come in to Costco to buy a six-month supply of the expensive blades. Devastatingly clever promo, ey? I’d do the same thing if I had to move a pricey product which stood the risk of sitting in inventory for too long since fewer people are willing to buy into what is, at its core, really just a Gillette vs. Schick pissing contest.
I’m a loyal Mach3 user, though I haven’t tried the four-blade Schick Quattro, but would like to to see how it compares with the five-blade Fusion, which I wasn’t bowled over with. Due to the fact that it’s got a quintet of blades, they have to be spaced much closer together and they are thinner as a result. In addition to this design characteristic contributing to faster wear of the blades themselves, this also has the tendency to cause uneven travel of the blades over the skin as the stubble accumulates in the smaller gaps between the blades more rapidly than on a three-blade razor. Sure, it shaves closer and smoother than the Mach3, but you have to rinse it out between strokes rather often to avoid the accumulation of stubble.
As others have said, the cartridge is a bit long, even with the thinner blade spacing. It’s probably a non-issue even if you don’t have a larger-than-average face, but it is indeed difficult to get under the nose (like painting a corner with a roller brush) and you’ll probably find yourself touching up with a good old single, double or triple blade razor afterward. (Hello, Sensor!) I found the single blade on the reverse side of the Fusion cartridge to be nigh useless for touch up … not exposed or “durable” enough for consistent results.
Sorry Gillette, I’m a loyal customer, but that Onion article was fairly spot on. I think this is one wheel that can’t be reinvented, at least not with this seemingly rushed design and certainly not for the price you’re charging.
