I continued trying the blade buddy for the past month in the same way that I did the first month, every other day, using a regular blade as a control. It’s looking pretty obvious now that the Blade Buddy works to some degree. Here is the final verdict:
Razor blade using Blade Buddy after 30 days of use. Some pitting, but not too bad:
Razor blade without using Blade Buddy after 30 days of use. Lots of pitting, getting pretty old and unusable at this point:
It’s nice to see a product that works as advertised. To be honest though, I’ve come to realize through this experiment that I can get away with using Gillette Trac II blades for a month without needing to replace them, so I’m not planning on continuing to use the Blade Buddy. One blade a month is good by me and that eliminates the need to use the Blade Buddy each time I shave.
