Kettlestack Adjustable KETTLEBELLS

I am considering purchasing a kettlestack. Since I'm a beginner, what is the minimum amount of weight I can set up with the kettlestacks? I see examples of 20 pounds, but heard it can go down to 15 pounds. I think 20 would be too heavy for me. What weight discs would I need for the minimum pounds?

Thanks!
