The Fatip design is a throwback, for better or worse. The alignment procedure is similar to a Gillette Old Type. Those razors have a similar loose tolerance between the blade and the posts. Loading upside down works on all mine, but I don't measure it, just go by eye. I'm not OCD about this.Also, outside of the Fatip handles, you really don't have a lot of options, which is also a big deal for those who have one or two favorite handles. The blade misalignment is also debatable. Some folks don't care if the blade is absolutely even on both sides while that makes others crazy if they can't do it.
I think the Fatip razors are really nice, but if the company spends a bit more time to improve them a bit more to absolutely eliminate the blade alignment issues as well as making them so they can use pretty much every handle, then they would become an absolute must even if the price is increased a bit.
Handles can be a downside, for sure. I've been using the Fatip wood handles. Pretty nice weight and balance, but non-standard threading, as noted. I also like the Piccolo handle, which is a bit too small for some.
