I bought it for my boyfriend. He exercises every day and uses a hake bottle mixer every morning and/or night to adjust the protein content. It never leaks when shaking and is easy to clean. The only part that is difficult to clean is the inside of the lid. There is a lot of space, but I only use chopsticks in it once a week, which is perfect work. The hake bottle mixer project is highly recommended.
I like to use hake bottle mixer protein bottle to make protein shakes. I usually mix a scoop of powder with 8-12 ounces of vanilla almond milk. This kind of vibrator helps the two to mix evenly, so no thick lumps are left. Easy to use, clean and water-proof.
This is a gift for boyfriend. He is very picky, so I never know what to buy for him. He likes hake bottle mixer gifts! He is an athlete and always needs a new bottle. I found the hake bottle mixer protein bottle. He said this is his favorite protein bottle, because everything he drank before was leaking. He said there was no omission at all! I am very happy with this purchase, and will buy more in the future.
