I'm a big fan of the twin neck dosing bottles, no need to touch the solution, or use syringes, or capfuls which can get messy. A gram scale is also a huge plus IME.

I really do like the twin neck bottles, never thought of that.

If i purchase two of these, my wife will stop hounding me for using her measuring spoons

Does anyone know where i can find the twin neck bottles and droppers in the Ottawa area that don't cost an arm and a leg?
