the handle on the M3 is not perfect, far from it. The best handle is the original Venus, now if they can cross that with the Vibrance it would be perfect. I still think the M3 handle is not as slick when wet compared to the Vibrance. I just don’t grab it by the end where there is no rubber. Still that doesn’t mean it’s great though. Can’t argue with the results though for either version. Maybe Gillette will revise the Vibrace handle to make it less slippery.
You’re right about the lube strip. It wears off very quickly. It is probably not a good guide to blade replacement.
