With all the Hype about Personna Med Preps and Labs, I decided to try some of them and also some Personna Barbers. Wow what a difference.
The Med Preps seemed to be close to an S.I. which means very good, almost as good as a Feather.
The Barbers were one of the few blades I have taken out after less than one pass. Before I took it (the Barber) out, I picked up another razor with an S.I. in it, just to make sure my prep was not to blame. After that the Barber went in the bin. I could probably get a better shave from my Kershaw Leek. I can't believe the same company is responsible for both the Med Preps and Barbers.
Incidentally I think I agree that the Med Preps and the Labs are essentially the same. If I ever run out of Feathers or S.Is. I know that the Med Preps/Labs will work. The Barbers were worse than the counterfeit S.I.s I bought last year.
