Even though the Fusion (similar to Mach3 I think), has 5 blades, the SensorExcel's 2 blades do a much better job of shaving and less irritation. I can even get that facial hair off my chin very well, nice and smooth, not like other razors..

Pros:

• Nice shave. No irritation. Better then Gillette Fusion, cheaper then Fusion too I think.

Cons:

• Don't think there is any. Except cartridges still aren't cheap.
