Official GMM hand model
I found this on ebay. No matter what you do. This is the best tester made and the price is killer. Goggle it and see what they list for. Need it once and not have it.. Well you probably have read the postings of the Horrible Freight testers that work for a few but not all. Get this while you can. I have one from several years ago and it was never used. The dog catcher got one also.
