I had a chance to have a good look at these before buying, and with tools I generally think you get what you pay for. But these are good chisels. Plenty good enough for my needs, and I really couldn't justify paying a lot more for Ashley Isles or Veritas.
I bought these to replace my old Marples which disappeared in a house move. After a couple of weeks using them I am very happy and like them a lot more. They required modest setting up out of the box. a little flattening and regrind, which is to be expected.
The balance feels natural and they seem to retain an edge well. I bought 6mm 10mm and 16mm which seems to cover most of my needs so far. But they are so cheap I will probably go back to get some others in due course.
