Review on PACK 20 Ounce Shaker Bottle Protein by Jodi Ward

Excellent plastic quality. The lid closes well and I had no problems with the cork opening unexpectedly. The size is great for my needs and better than carrying around a large bottle when you don't need a lot of liquid. Of the minuses, there are two things you should pay attention to. 1. There is no loop/bracket on the top like you may have seen/experienced with other brands like Blender Bottle. It's okay, but something to consider.2. The plastic is very strong BUT this poses a few practical problems. First, the measuring scale is small and with little relief. Since everything is monochromatic, it's VERY hard to see the markings except in better light. And second, you need very good light to mix them when measuring in a bottle. Especially with color versions. darker tones like purple make it virtually IMPOSSIBLE to see the liquid level through the plastic. You should use your phone's flashlight function or put it in front of a bright window to see the levels. I even mark my level with a marker so I know when it hits the fill point. A little tedious, but there is a workaround. Keep in mind that the white version is best for blending, but all but Eagle Eye will probably still need some help filling. I have uploaded some photos for your reference. Overall a good product but be aware of these issues before purchasing. All the best.
