Hello everyone. My wife was given a gift that had some shower gel in it and a Schick Quatro cartridge razor in it. She wanted me to use it first before she did. I lathered with VDH and an AOS travel badger brush. I had forgotten how to use a cartridge razor now that I am use to DE. I was shocked at how forgiving a 4 blade razor is. It can not cut you. It will glide over bumps and go out curves like your chin in one motion. If you do that with a DE you will cut your face off. I did get a smooth shave from it but at a cost. I now have bumps under my nose and my face still stings...razor burn I would guess. I tried to use it like my DE...WTG, XTG, and ATG....three passes. Yes, it is faster to use than a DE and would be good in a pinch if you are in a hurry. I am not going back...I will stay with my Lord Merkur Tech. The 4 blade cartridge was smooth with no drag. There was no real feedback and not much audio either. I like the feedback that I get from a DE....I know I am shaving something. I had to try it just to see what the difference was now that I am getting better DE shaves on a daily basis. When all was said and done, my AS told the story of my shave. BURN!!....that says it all. I must have razor burn after my cartridge shave. Now I know.
