This is a oneblade core without the expensive and single choice blades (almost).
You want to ditch cartridges and go for the much cheaper de (Half de=se) blades or want more choice this comes close.
Plus
Easy blade loading
Infinite blade choice since it uses halved (broken in half or pre cut) standard double edged blades.
Blades are 10-20 cent easily lasts week(s). It is not blade picky shaves decent with many and blades are worldwide easily available.
The pivot sets the right angle.
Even with some pressure still forgiving
Does not clog!
Affordable
Intuïtief
I like heavy this is.
Cons
This is mild shaving so if you want medium insert a Kai, bic, nacet.
Head is wide under the nose
Plastic top cap could break
Biggest drawback is the manufacturer who rarely answers an email. And the razors are afaik permanently sold out.
So I opted for an other razor as a travel machine because replacing it might be a problem....
