Good at first

Would Not Recommend

When I first purchased the pro gun and cans, I couldn't believe I had taken this long to get one. They were great at first, but I feel like my last 2 cans seem like the manufacturer has shorted us a thread or 2, and you can't get the can locked in before foam starts coming out. I'll be switching to Locktite.
