Highly recommend to mix my creatine and electrolytes!
Use it everyday! great for mixing my protein powder drink after my workouts. i have a 12.5 oz and a 24 oz. the 24 oz even mixes quickly! so nice not to have to shake my bottle and still not mix the ingredients well.
I had problems with the VISP working they replaced it immediately at no charge. The response was better than I thought possible.
