I'd have a lot more respect for Muhle if they came out and openly said they messed this one up and would replace anybody's head with the latest attempt at no cost - as there must be many, many people who've bought this who don't frequent forums and realise there are bigger problems, and just written it off as a razor that's not for them, possibly to reside unused in a drawer somewhere.
This continual releasing of new versions, which still aren't right, is worse than the rubbishest dodgy kickstarter I've seen.
The fact that suppliers are promoting they have the 'latest v3' in stock is silly when there are still known/the same problems with this version (apologies to suppliers, but it's true).
I await the v4 in due course.
