Tried one of these for the first time last night (part of my sample pack) and I have to say I'm mightily impressed - possibly one of the best shaves I've had!
Tried a feather & a Shark SS last week & didn't really get on with either (shark was fantastic for a head shave but not so good for my face?).
Anyway the 7 o'clock SP blade was a joy for both face & head! Really smooth and a super close shave! All I need to find out now is how many shaves I can get per blade & this could be purchased in high quantity for my daily blade of choice!
Still got lots more from the sample pack to try but this is a definite contender so far
