24oz Stainless Steel Protein Shaker with a Built-in 6.5 oz Powder Container and a Built-in Agitator

This shaker tends to leak at least 50 percent of the time. The seal and the design of the stainless lip and its interface with the top are most likely to blame. Plastic shaker bottles that I have had in the past that did not have a rubber seal never leaked. Also I hate that I cannot remove the logo. Not my best purchase:(

Had issues with seal on both bottles. The bottle itself was great and did the job. The only issue was when shaking, the bottle it would leak. I sent back and got refund with no issues.

It's pretty to look at, but that is it. I bought this for 2 reasons, 1) A nice looking protein shaker that I can use in the office 2) A protein shaker that doesn't leak. Unfortunately, it leaks and i was so disappointed. It now sits in by cupboard and I'm back to using my old shaker.,

I bought this because it said it was a thermos too....it is NOT. This is just a stainless steal shaker. Other than that, it's great.

Although I liked the design, material and price, it leaks! It was great the first few times but not sure why it started leaking later.

I love this bottle. its easy to clean and big enough you wont make a mess when putting protein or any other kind of powder in it.

I know it said “dishwasher safe, hand wash recommended”, what I didn’t know was that once through the dishwasher would cause the metal on the bottom to come off. Disappointing.

The aerator stuck to the top is annoying to clean, but otherwise it works well. It has close to zero insulation and pretty thin material, so it's not going to keep things cold or hot for very long.
