The original manufacturer of these cheap readouts is SanJian Studio. The problem with the Chinese is that they don't just pirate from other countries but also from each other! As long as they are getting good feedback they should be OK.
It's too bad that they don't have a 3/8 " digit version as they would be easier to fit into the FRG-7.
When I buy from China using Standard SpeedPak it usually takes 2 weeks to Canada. But with Covid delays Amazon would be faster.
I did search for the cases as well. They are probably coming from one of the USA Electronics surplus companies.
