The gun performed as expected when using PC Products clear epoxy applied through the mix tip. I've dug up dozens of DP-604 cartridges over the years and found this dispenser gun to be as simple and effective as any I've used. Everything appears to be built to spec and should last for years with occasional use. I paid <$10 and the product is up to $25 with a competitive price. but the current $18.49 is fair given the cost of the production molds. If you don't like the real thing, 3D print your own.
