yes I have used there injector and it's pretty good. you have to get used to it but once you've done a few repairs it's smooth from there on. it's a different injector system than the rest of them on the market for sure, there holding structure does'nt need to be adjusted like the other's with two screws at the other end. there is more area for viewing a repair between the cup and injector, when putting pressure on the repair you can see the white tip expand easily compared to the stainless injectors that have a different white tip and you can't see them expand as easilly.
