Duo Classic Protein Shaker Bottle, 24 oz. (Black)

I pretty much hate giving 5 star reviews, and I'm about as unforgiving as a Michelin secret inspector at a two-star restaurant, but this bottle exceeded my expectations. I haven't had any of the issues relating to leaking that some other people wrote about, and other than the one time I got greedy and put in two scoops of protein instead of one, clumps have largely been a non-issue. The straw works well, and the bottle is so nice that I'm sometimes tempted to take it around for no reason. I followed the company since it revealed the product on Kickstarter, though I only made my purchase recently due to my own, old blender bottle breaking. The mechanism for sipping isn't that great in my opinion, though it's adequate. The straw folds out with a little too much friction, and I think some aspects of the bottle could have definitely been improved, but the bottle was good enough for me to still give it a 5/5, despite some of it's limitations. Overall, though, I'd probably give it a 4.5 instead, if I'm being entirely honest.

This is my new favorite water bottle / protein shaker / preworkout shaker. It fits perfectly in my cup holders and does a great job blending powders in water. I had a lot of trouble with blender bottles because I could never open them up without using great force and spilling liquid everywhere. This is so easy to open and use because of the straw feature. Plus i can get out all the remaining liquid using the spout feature. I am obsessed. Great design.

always leaks out in the sip cap area. I just superglued it and decided to just use the straw feature

This bottle is perfect; it blends well, doesn't leak, is easy to clean, AND fits in your cup holder. Not to mention it is beaetiful! Form AND function. I've tried BlenderBottle, which should be called the DoesnotBlenderBottle, the Fit & Fresh Jaxx Shaker, again, should be the Wet & Pissed as it will cover you in your drink when you shake it, and numerous other shaker bottles. TRIMR is hands down the best. I highly recommend this if you're looking for a shaker, or even just a water bottle.

Works well but you not really dishwasher safe. The lid and straw melted in the dishwasher after a few washes.

Love my water bottle!! It's so convinient, especially because it comes with a straw! I love bottles that have some sort of nozzle or straw because it makes me want to drink more water for some reason lol!! I got the black one and I love it!! So sleek!! ^_^

This has got to be the most expensive worst shaker bottle I've ever purchased leaks like a sieve I do not recommend this product and I guess I'll be reading my return options on future purchases because you can't just return it to The UPS Store like you do most Amazon returns oh no you got to print out a whole label take it to the post office all this mess so I guess I got took this time won't order from this company again and Amazon I thought you hand certain standards and return policys for your seller's

This Ian the best shaker Botle that I've ever bought. And I don't usually praise things. It's solid, has the option to suck through a straw or drink straight out of the bottle. And the lid doesn't smack you in the face when you tilt it up to drink. The mixer is rigid and actually forces the liquid to mix instead of a flexible ball that hardly does anything.
