This Hypo is without a doubt the most accurate TOS Hypo replica ever fabricated by any other propmakers. And that includes the biggest names in prop making such as HMS and SD Studios, who for whatever reason never were able to get it quite right. Plus, the Vials are spot on and you can't beat the ability to field strip the parts just like the original. There is nothing quite like a screen accurate prop replica like this. I have a red, orange and green and now i'm thinking about also getting a Blue vial once my finances recouperate. Great job Scott! :thumbsup
