Great! The spray is very fine and uniform, which is what my flowers need!

Bought a Miracle-Gro in-line fertilizer a few decades ago, and the plastic bottle formed little cracks this year and started squirting a little jet of water. Miracl-Gro no longer makes their in-line model. I tried plastic repair epoxy, but it still leaked a bit. Saw the Groundwork version in the store and bought one. Yes, the gasket is a bit thin. If I don't screw the bottle on tighr, it leaks. Might have to make a better gasket. I use it without the sprayer; without the sprayer, it has hose connectors on both ends. [I use Gilmour quick-connect hose ends. With two of those, it's a pretty good replacement for the Miracle-Gro. The bottle seems to be the same plastic, so, I'll buy a few spares...

Waste of $10, I was so happy to find this after years of trying to find a viable replacement for the old style miracle grow sprayer. It sprays water out of the white valve connector between the hose end attachment and the bottle. There’s a flat washer and an O ring washer on the valve. No matter how tightly I attach the hose the white valve doesn’t seal and water comes shooting out.

Container will not seal to top. The rubber seal doesn't seat properly inline with top so more solution comes out around top than is sprayed out of end. Really a piece of garbage
