i too bought some
they are smaller -1:24
the size difference, imho, is neglible and they can be used right next to 1 :22 figures and it look like simply the difference in normal human heights
the detail is less than crisp-in fact, pretty poor.
they are poor copies, imho, of preisers
I agree buy them painted, as I bought mine unpainted and,
while I like to paint, and often it can do wonders,
simply, they are suitable imho for background, inside coaches and buildings etc where detail cannot be closely scrutinized. As such, I think it worth your time to have them painted and then touch up or detail as you like. I found painting the 25 or more I bought, even crudely, was quite time consuming.
in my batch, there are many multiple of a single figure. this gets old and easily recognizable unless , imho, used as faces for a window in a coach or café, etc.
