Honestly, I was skeptical about the garden-hose hookup, but it’s so much quicker than hauling water. The auto-shutoff at the correct PSI is dead-on, and I’ve used it three times now without a single leak.

The quick-connect fitting is a game-changer—I just snap the hose on and the tank hits the right pressure on its own. Worked flawlessly on the first try and saves me a ton of fumbling around.

I was skeptical about getting the right pressure without fiddling with gauges, but this cap handles the auto shutoff perfectly every time. My tank is ready to go in about two minutes flat, even when I'm filling it away from home.
