Tried my Nutribullet RX today for the first time. I used spinach, blueberries, banana, a few grapes, chia seeds, flax seeds, coconut water & a touch of honey. It tasted yucky! And the seeds didn't blast very well, it was grainy. Hoping I get better with this and find some flavors I can live with. Disappointed on my first day, but I will keep trying!
