Cram, they're pretty good.
They can be pulled in one direction slightly then let loose and they twang back, suggesting the plastic is durable.
As with subbuteo...carefully does it.
I've had no issues in the boxes I've purchased in the last few months.
My only gripe is that the first generic box out can be awkward on occasion if you intend to 'animate' your figures but I guess their purpose is figs on the table rather than conversions.
