+1 to the usefulness of Sugru!
I got on the Dorco bandwagon earlier this year, thinking the blades would be the same as Gillette – but they’re not. I have done many tests using the Dorco blades and blased from Harrys – both against Gillette. There is no comparison that Gillette blades provide the closer shave. Harrys blades come in a close second. Dorco blades are good for the first use, but the quality deteriorates fast after… and the blades with the yellow strip are almost useless as they cut my face no matter how careful I am while using them to shave.
