Blade Biter
I assume you shave your beard too? Then your 3 shaves are more like other people's 6!That's a good sign of a quality business. Mistakes get made and they reacted perfectly.
I've now pretty much settled on three shaves for a DE blade. It's taken me a while to get to the point where I can now appreciate the sharpness of a fresh blade, without worrying about getting bit by it. The second use is usually the best compromise of sharp, but not too sharp and comfortable. By the third shave I can tell the blade has degraded.
I hope you have a great vacation!
Maybe 9 considering there (usually) are more on top.
