Very sturdy
This is a great shaker bottle that is of sturdy plastic with a blender ball.  It is quite large but not too large and gaudy. The lid screws on and then has a spout to open for drinking. The lid seals nice and tight and there was no leaking while I was shaking my drink. When I first tried to open the drinking spout it was too hard it sealed so tightly and I had to have my daughter open it but once she opened it three or four times in a row it loosened up just enough to make it easier to open but still keep a tight seal. It has no handle to carry it with but it is a comfortable feel to carry without a handle as it has finger indentations to allow a better grip. It also has measurements on the opposite side. All in all it serves its purpose well and I am happy with it.
