The voltrx electric shaker bottle is pretty good. Especially the price.

　　The lid of the mouthpiece slammed shut. Anyway, I use my fingers to shake the lid, because I am more paranoid, but it may be able to withstand some very rough shaking without opening or leaking. It can pass the electric protein shaker without difficulty. The plastic will not warp and the lid can be tightened comfortably. The size and density of the whisk is just right. My electric protein shaker bottle is completely mixed and there is no lumps. Very happy. I bought two.

　　Give me one before exercise and one after exercise.

　　I like this electric shaker! Recently I started to drink protein drinks, I need something like this, it may be the only thing I drink. I also don't like drinking water, so when I don't use it for mixing protein powder, I use it as a normal electric shaker bottle. Fortunately I got it! Since I got it, I have used it often.
