I have used the 21 cent and I did not like the black caliber change spout. It was long or overly large, and made it difficult to see the charge being completely in the case (at least with a BRA sized case). Kinda defeated the purpose of the clear tube. Just my opinionDoes anybody use the ones from 21st Century? I like the idea of the clear tube. I'm thinking the 10" one???
