Good system overall, more expensive then many other alternatives and to me the benefit was its flexibility to find a solution to all life / work styles. I must say I find it extremely difficult to book classes on an ongoing basis... as I'm working full time and travelling most of the time, so if you miss Thursday mornings its very likely you'll miss a few weeks... which is not ideal. So SFS promise of offering flexibility for all life/ working styles is not fully delivered. This is my second enrollment and I'm seriously thinking not to continue after this one finishes- thanks and kind regards
