This is a great shaker bottle. It seals well, screws on and off easy enough, and has a little clip for your bad, and tapers enough to fit in larger cup holders or in side backpack pockets. I also liked that it came in colors, the ones I had before me and my buddy confused them because they where the same color and bottle, now we know whos is whos which seems silly to like but its nice. Only thing I wish it had was a spot for pills that wasnt a lower ***** on piece, like a little pop top compartment up top, but no bottle is perfect. It mixes all types of powders well I mainly use weigh isolate and Bcaa in it. It washes out well and seems not to hold any real stank which is nice, being mine sit in a car for a day at a time while Im at work.

The product description is a bit misleading. It says the main container holds 20oz liquid. While this is factually accurate, the stated measurement capacity on the side is 12oz. I would NEVER put the max in there. It probably wouldn't mix properly as there's no room for it to mix.

Best shakers hands down! I have about 6 of them and they never disappoint.
