Had my 3rd shave with this razor and at the moment I'm not that keen. The cutting angle on baseplates 2 and 3 seem a bit odd to me. By altering the angle of attack, it goes from not cutting anything to presenting the blade at a hair-scraping (rather than slicing) angle very quickly. Oddly, it doesn't seem to cause the amount of irritation I would expect from an uncomfortable shave and I also end up with a great result. It's a tricky little blighter!
I'll give a couple more baseplates a try before I give up on it completely though.
