Left Cornerstone a few months ago after they changed the razor which is significantly inferior to the original razor. The blades did not feel as sharp, did not cut after a couple of days and were extremely difficult to clean - especially with their own gel. I'm only writing this review after they sent me an automated email today inviting me back and suggesting I read the reviews on this site. Negative reviews seem to be met with "contact help@cornerstone.co.uk". I did his on my exit from Cornerstone but they took no notice of me. My gut feeling is the newer product is a "miss" so I'm back to using my Merkur Futur. Will maybe try again in a year or so if the company acts on its customer feedback.
