I was given a few packets of these as a freebie and asked to try them out. After seeing where they were made, I really wasn't expecting much from them at all. I loaded one in my Parker 99R Butterfly which gives a pretty aggressive shave with the Astra blades I normally use.
In the Parker, they actually felt quite dull so my suspicions were correct. However, after rinsing off, I was surprised at how smooth my skin was, they shaved better than the Astra's. Now I'm really hoping that someone will stock them as I really want more.
