To start... I used a few smaller bottles and half the ingredients. There were no starting problems. Nothing leaks and it has a non-return valve for the night. However, I found the needle adjustment valve a bit difficult to adjust. When the valve is closed (tightened by hand) it still lets a decent amount of CO2 through. You almost have to pull it down to shrink it to 1 bubble in 3 seconds. I'm sure there are better valves out there as this type is probably for higher pressure applications. Otherwise, I am very satisfied. (sorry for the graininess of the picture)
