You tried all the other new ones when they came out. 3 blades, 4 blades, 5. But instead of just adding another blade or a vibrator and calling it revolutionary, the Hyperglide is all about the lube. Yeah, it’s got a patented superhydrophilic self-lubricating cartridge that creates its own slippery HydroGel over the entire front shaving surface. Just add water.
