The voltrx protein shake blender is durable and easy to clean!

　　I bought this protein shake shaker for my boyfriend as a birthday present because he was looking for a juice bottle to take to the gym. Not as cheap as what you find on Marshall's or TJMaxx, but the green color is too unique to pass up! This cup mixer for shakes is good quality and very durable. It's also easy to clean and dishwasher friendly!

　　It's bigger than I thought it would be, but mixes protein drinks very well. Well made, has a vortex shaker cup that is very old and still looks new.

　　I use this shaker bottle electric for protein powder. It breaks up everything that is not a lump of any shape. I recommend this product, it comes in a variety of colors to choose from.

　　I think the key is the metal ball in the electric bottle. It mixes my protein shakes much better with the different blenders I've tried than other brands. If you need a quick sports drink, I recommend getting this bottle shaker protein product.
