After 14 days of using the Shaker Plus for 30-40 mins twice daily I broke my magic 5 liter volume barrier. My max was 4.8. Magic! I was expecting improvements in maybe a month or two. I'm lost for words. I knew it was only a matter of time as I could sense the improvements were there. I thought maybe in a month or so, but this is outrageous... To break 5 liters for volume first time ever. I've only had it less than 2 weeks — 30-40 mins twice daily. Obsessive? Regards Edward.
