These are large electric shakers that are reasonably priced. I like things that a lot of cheap wine merchants don’t have:
lock the lid tightly
Removable plastic screen to prevent ice cubes from falling while drinking
There is a rubber handle on the lid, so it is easy to tighten or loosen the shaker mixer machine lid
I have 4 best electric protein shaker labels they hold, and they have been working for me for several months. I just threw them in my sports bag and never missed anything!
Actually, when I bought it, I didn’t know it was 2 packs, so I was surprised. This electric protein shaker nz is very large and can hold a lot of water. I use it during morning exercises. I really like to use the unscrewed compartment to fix the protein powder until I finish the exercise. The only thing to pay attention to is to clean the protein shaker mixer. There is a crack on the top that can capture some powder and shape it at one time because I missed the cleaning. It will be cleaned up soon, but I will pay more attention now.
