It's infrequent that we find prop replicas that are better than the original, but we think this screen-accurate combadge from Star Trek: Voyager qualifies. The screen-worn originals attached using hook-and-loop. Good if the actors have to wear something frequently and you want to make sure they put it in the same place every week. Not great if you have a pristine uniform you'd like to be able to wear without the combadge on occasion.
This version attaches with embedded magnets, giving you flexibility the original actors didn't have. Also, the screen-worn originals were made from painted resin; these replicas are made from metal. That means they shine in a way that the cameras wouldn't have loved, but we definitely do. We think if you've bought this snazzy reproduction, you should show it off.
