FUELSHAKER Ice Series Shaker Bottle with Fueler. 2016 Model (Classic Red)

Bought the ice blue and teal one the first time, and the agitator did not fit in either. Returned and bought 2 teal bottles, and the agitators still didn't fit. So I took a pair of scissors and carefully trimmed off a little of the rubber from the agitators and they both work fine now. I probably should've just done that with the first 2 bottles but oh well, not a bad product. My boyfriend likes it.

Love this thing. Beats using 2 bottles!! will never look back again!
