I can shave under my nose using a diagonal stroke, I haven't liked then as they are not smooth. It's not like they are tugging, but just feel uncomfortable. They with Bic are the worst cartridges. Dorco are better.I used to have the very similar Cornerstone razor. First impressions were okayish and then I realised it was just plain crap in every sense.
Possibly the worse multi-blade I have come across. Far too large and far too flexible to be of any practical use and even Mrs Satanfriendly declared it useless
