YMMV for me and even for regular shavers I spoke with (who usually use top of the line carts like Fusion power xyz system) disposables are the worst of shaving industry - dull, inefficient but still can bite you and after few uses are useless. And I’m not even talking environmental side of it.The cheap twin disposable shaves WAY BETTER than any DE razor I’ve ever tried.
Good that you find them usable but if I would have to return to carts, it would definitely never be these cheap ones… I still remember how bad was shaving with them.
