Whoa, whoa, whoa... I know we can alter GEM blades to fit, but what KAI blades fit????The Hybrid is actually pretty good, much more efficient than the Core, smooth, and easy to use. I'm getting 4 good shaves per blade, but haven't used a KAI or GEM blade yet. The Hybrid is a keeper, and I had returned the Core.
Basically 95% of the Genesis, at a whole lot less money.
I have the mostly the same experience as you, but I do get the same blade life regardless of Hybrid or Core. I get two good shaves and can get two lesser shaves.Unlike the Core, which gave 1 decently good shave, then 1 meh shave, the Hybrid is good for 3 quite good shaves, and 1 that takes a bit more work on a single FHS-10 blade for me. - I have stiff gray growth, so there's absolutely a huge improvement over the Core I tried in 2017. It's actually possible to get a weeper or tiny nick with a Hybrid, if you're sloppy enough, and press way too much.
