Top Shaker and Blender 14 Oz Colors May Vary

This shaker is the perfect size for 8 oz. of liquid plus protein (or other) powder. I really don't need or want a 16 oz. or larger size. I found that even hard to mix whey protein mixes up smoothly even without the blender. By the way, when they say "blender", they are referring to a metal spring that supposedly helps the mixing process. I don't need it.My only complaint is that the bottom of the cup is too large to fit in my car's cup holder. Soooo close to five stars.

these work just as good as the blender bottle...just be careful to always rinse these out with water after you drink your shake. if you forget to do that, the smell in the cup is absolutely horrible and the plastic absorbs the smell. i've had to throw two out because of it even after filling the bottle with water and baking soda.

These are a perfect size for the drinks and shakes that I use. The oz are listed on the side for you to make sure you are me surfing correctly. Cap screws on tight and the spout closes securely. I make sure mine "snap" closed so that I don't start shaking my drink and have it go everywhere. I also put my finger over it, although it isn't needed. It's a habit from other shakers that I've used in the past.

The shaker bottles are great for anyone on-the-go. I like having multiple bottles that way while one or two are being washed, I can always have an extra to use. The build quality is good. I've used them multiple times and after I use them, I run them through the dishwasher and there is never any residual odor from when I've left used bottles sitting too long. I plan to purchase more in the future.

I ordered three of these for protein shakes. My daughter loves hers and I am using mine instead of my older tupperware model. The spring type ball assists in mixing rapidly and without much effort. The screw on lid is easy to put on and take off and has sealed each time with no drips. It has also been easy to clean.

These have worked out great. Love that it came with 3, so now both my kids and myself have our own blender bottle. They are great quality and great price. I will most likely buy more, as someone is bound to forget their shake and let it rot in the blender bottle. (We've all been there I hope haha) But I would buy again.

Nice shakers at a good price. Not really much to say as they function as they should. Seal tightly and thread easily. Perfect size for popular 8 OZ shakes. We needed a few extra and these fit the bill. Depending on longevity (and they appear to be of good quality), will probably buy more in the future.

Good product for the price. Been using for about six months now without a problem. I use the top rack of the dishwasher to wash.
