Default magnetic yeast starter

I usally use an empty growler with an airlock for my yeast starter, is there a significant advantage to using that spinning magnetic yeast starter?

yes, it almost doubles the cell count. Because it keeps the yeast cells in solution better than if they settle out they can multiply more quickly. It also draws in more oxygen which helps growth. Consider using sanitized foil on the top instead of an airlock and swirl a few times a day and it should improve also

How long in advance do you set this up before brew day? I usally do it about 1 1/2 days in advance
