Nice finish but don't last

They look quite nice and the glossy effect from the acrylic gives them a nice finish, but the printing on the back is unprotected and the glue holding the back is prone to slipping or softening at body heat. More than half of my team complained that the back was scratched (ruining the graphic displayed on the front) or the pin had either moved, bent or fallen off within two weeks of distributing them. I'd say their saving compared to enamel is wiped out by the cost of such frequent replacement.
