1. The ads and online info keep it a deep, dark secret that Gillette3 works with a Mach3 handle and Gillette5 with Fusion. You don't need to spend money on the new handles.
2. Pricing is all over the map. I wanted to see how cheap I could get some, so I forgot about the Gillette5 and concentrated on the Gillette3 (I think one blade is enough, so 3 beats 5 anyway). The best price for each Gillette3 cart was slightly over one dollar each. I got a package in Walmart, but the price rose right away after that. But, now Ebay has 8 for $9.50, including shipping, so the rock bottom price looks like around $1 to $1.20, even though some places get two bucks or even $2.50 each. One dollar looks pretty aggressive for a new Gillette 3-blade cart. The only thing it lacks compared to the G-5 is the trimmer blade.
I tried it twice and, to be honest, I got the identical shave I get from DE and SE, except there's zero irritation. I occasionally get some minimal irritation from DE/SE, because you can angle it wrong. The Gillette cart does the angling for you, just like the automatic transmission on a car, compared to manual. Less fun and less irritation.
