voltrx protein shaker blender with leak-proof lid

　　We love this voltrx electric shaker, and the signature wire stirring ball that gets the job done right. If you're looking for a swivel cap, this is our top pick. It also has a sleek design. They also make the exact same insulated stainless steel model that performed well in our tests. This is great for mixing drinks and making sure you have enough water to drink throughout the day. Metal shakers are very good at mixing. One tip I learned is that you should always add some liquid before adding the protein powder. That way, all the powder won't get stuck in the bottom of the bottle.This glass oscillating bottle is easy to clean, just add warm water.
