Yesterday whilst picking up a few bits and bobs at the Rexall, I seen this Personna made razor labeled X3. For the whole 5.99$ it cost I figured why not? Anyway, I take it out and the blade heads are a little fatter than a Mach3, but the blades look exactly the same. They do snap on though with a Sensor type grab but after fiddling with it, Sensor blades don't quite go on, which was a strong hope since the handle is amazing and well weighted. So, I shaved with it tonight and I will say the shave is exactly that of a Mach3 with no difference in feel. I will state though this one gave me less irritation. I'm not comfortable with the 'fat' heads so that's the draw back for me, but with a similar design to the Sensor the pivot is easier to shave with than Mach3's floppy head. The 4 pack of replacements was 4.99$ so it is a very highly recommended alternative for those who use the Mach3, I would definitely consider trying it.
Also: for anyone interested the Rexall seems to have an amazing selection, including TracII Personna's, a 15 pack for 3.99$ (not the dual fit blades)
