No I'm not!
Over the years I have handed 2.5kg of non functioning residual pressure valves to work cover NSW. Have had more than a couple come through with cutting oil (adds a great taste to beer) and or swarf from the neck threading still in the bottle. Several with beer in them, which just shouldn’t hapen.
With the admittedly more expensive MKOL and similar high quality kegs, zero problems.
It's a personal decision but I just don’t take chances with pressure vessels.
