Simple and well made
All pieces are solid and fit together well. Pretty much plug and play to set up and use.
BUT THESE, you will need them
You will never find one of these when you need them. Buy at least three and they will come in handy, i'm speaking from experience. These are a great price and have a quality feel too. I recommend to buy three, especially if you are running any kind of dosing system.
1/8" Micro Valve
Used this micro valve on a custom built kalkwasser doser. Allows you to adjust drip rate precisely and does not clog. Good quality plastic so it doesn't feel flimsy. Overall good product!
