MANSCAPED® Weed Whacker® 2.0 Replacement Blade Cartridge for Electric Nose & Ear Hair Trimmer, Twist-On Replaceable Clipper Blades, Improved Sharp Dual Rotary Blade for Precision Cutting, 1 Pack

The instructions that come with the "Weed Whacker 2.0" say, "For optimal performance and hygienic operation, blade should be replaced EVERY 3 MONTHS" (yes, in CAPITALS, with a suggestion to sign up for an automatic "replenishment plan"). To charge more than half the price of the whole machine for such a small replacement part is OUTRAGEOUS. It is a comparatively expensive machine to start off with but I chose it because it got the Best Buy recommendation from Which? No matter how good it is, I wish I hadn't.
