Mach 3 generic cart blade disappointment

On my last purchase of Mach 3 blades I thought I would try the drugstore brand of replacement blades & save a bit of $. BIG MISTAKE. I really disliked them- bulky & awkward pivot, poorly designed lubricating strip, etc. 

Is this the norm for other brands as well? Have you used the generics and been satisfied?

I started DE shaving after using using some Mach 3 blades purchased on Amazon.  No English characters on the package.

I've used some generics that are made in South Korea, those seem to work well and are a bit cheaper than the Mach 3. However, they use a different system for the cartridge.
