How does the fusion compare to the fusion proglide?

Zero from a customer standpoint not sure from a brand perspective it might just be one less blade vs more on one I noticed this in the one that came out with the cooling side feature if u will a little while back just bad an extra ade so when u nick urself on rare occasion I always look at that n think we'll that's just the # of nick's aka cuts ur gonna experience if or win ya cut urself ever w/it. That's all I fig on blade count. I'm also a women that loves & uses this shaver i LOVE THE 2 PROGLIDE & FUSION 5 no diff tho I see just handle design i did notice the Orange one I think it's the Fusion 5 model that has a really pivoted head that moves quite a lot with all my leg angles & things like that where the Fusion without the orange on it doesn't tend to pivot as much the orange is my absolute fav for that reason alone it's crazy how much the head confimorms to ur body which does rest in an awesome close shave & being an Italian woman I def appreciate that so very much! This IS MY shaver has been for so many yrs don't recall using others. I love this thing I'd die without it. ;)
