Good overall but cheap plastic
This was a great shaker bottle, at first... The opening is big enough so you can put your fingers in to wash it entirely. It's easy to use and works well. However, I dropped it from waist height onto concrete as I was leaving the gym and it split open on the bottom. Yeah, it was a careless mistake and it was heavy due to it being half-full but I expected it to be a little sturdier, but it is only $5.. I ended up purchasing a BlenderBottle Sport Mixer, which claims to have higher quality plastic and BPA-free. But if you're looking for a cheap, plain (something that doesn't advertise random brands) and a decent all-around shaker bottle, this is still a good deal.
