Thermos Vacuum Insulated Stainless Steel Shaker Bottle with Integrated Stationary Mixer, 24-Ounce, Stainless Steel (3 Units)

Overall i think thermos has the best product in its class currently. The capacity of this bottle is great, the insulating properties are excellent, and they have a few unique features that help put it above the competition.Pros:-Double wall vacuum sealed bottle does a great job at insulating. My shake stays cold long enough that I don't notice any change in temperature by the last sip.-Modern creased design and minimal accent colors is attractive and easy to grip-Internal graduations embossed in the steel-proprietary mixing mechanism is far superior to shaker ball. I use mine in an office setting so a loud shaker ball is not appropriate. The mixing is near silent with this and the mixing ability is on par.-has locking feature so lid cant come open inadvertently-wide mouth makes drinking thicker shakes more tolerable-features a keychain hookCons:-Clear Lid mechanism isn't great. There are plenty of separate pieces to the lid which adds more opportunity for your shake residue to flow into crevices and build up over time.-The lid does not have any auto sealing ability like some Contigo mugs, which would be nice for an office setting. (I don't want to accidentally spill my shake all over my papers)-There is a rubber plug in the clear lid that butts against the spout when closed. When the lid flips open, any liquid on the rubber plug drips down in the clear lid which is going to get in the aforementioned crevices and build up. A redesigned lid would really help this product shine.-The latching mechanism relies on some thinner plastic on the clear part of the lid which I expect will eventually break.-The button to open the lid is also funky. Pushing the button halfway will release the lid, but pushing it fully will not.-No window. You have to guess how much is left in the bottle, as there is no way to see in like some other brands-Plastic lid means possibility to crack or stain over time. A metal lid with rubber seals would be more durable.-Spout is located toward the center. You need to tip this bottle back really far to actually drink all the liquid. If the spout were closer to the side of the bottle it would pour out easier.

This bottle is “almost” perfect, and better than any of the many others I’ve tried.1. It’s super-easy to clean and the protein powder doesn’t seem to get in any of the cracks and crevices. It’s also dishwasher safe.2. The lid has a flip lock, so you know it’s closed tightly. I haven’t carried it anywhere sideways so I can’t say it definitely doesn’t leak, but I’ve had no issues with it leaking.3. It’s insulated and keeps your drink cold for hours (could also double as a cold water bottle if necessary)4. It’s easy to hold! I have smaller hands and this can definitely be an issue for me.The measurement lines are inside the bottle and a little difficult to read when just adding water, but this is a small issue for me with the other benefits.Highly recommend.

This Thermos states that it keeps things cold up to 16 hours; however, it doesn't live up the other Thermos insulated products we have, that really does perform. This one doesn't keep liquids ice cold for very long, a few hours.Also, I bought this to mix protein powder shakes. The fixed green agitator used for shaking/mixing of powder with water does not perform a thorough job, so the outcome is still chalky like. I bought the blender bottle, after this Thermos, with the stainless steel ball, that does the job because the ball sloshes/rolls around for a better agitator. The bad thing about the blender bottle, is that the bottle is plastic, so no insulation, to keep liquids cold. So what do you do, remove the green agitator from Thermos and throw in the steel ball.Thermos, it's time for re-thinking.

This is a great shaker for making protein shakes in. I have had no issues with leaks and it's very easy to clean. The agitator does a nice job breaking up the protein powder. And the best feature to me is that the closing mechanism is a screw on top and plastic flip spout cover that is very quiet to use in the mornings. Other bottles that I have had were noisy to close and woke up my baby (not toddler) who is an light sleeping early riser.

Overall the product itself isn't too terrible, but the lid is super cheap and doesn't last long if you wash it. Even hand washing, the lid is easily ruined. I've gone through two and I just give up.After washing the lid, the seal won't hold any more and leaks whenever I shake it. It really sucks. I'm gonna have to go for a name brand shaker instead of this cheap POS.

Love this new shaker. Easy to clean enough room for up to 20 ounces. Keeps warm or cold for several hours. Only thing i dont like is the catch to keep the lid closed pops off to easy. Barly hit it once shaking the bottle and it exploded lol. So keep your hand off the lid.

I usually put a sports drink in this thing with a cube of Ice and it stays cold for hours. Sturdy too. Shakes up the drink just fine. I recommend it item.

The shaker bottle is great! It keeps fluids cold for a long time, great for protein shakes and the lock on the lid stays the fluid secure.

Si mantiene el agua fría, si puedes poner agua caliente en él, no te quemas al agarrarlo, pero no es bueno taparlo completamente con la tapa, se destapa, muy bueno para uso de shaker, se disuelve muy bien la proteína, estaría bueno que hubiera de a litro, cuidado con las caídas, se abolla fácilmente

Product started to leak while using it as a shaker after a few months. I'm very disappointed by this product, can't believe it is a Thermos. Paid a premium price for a lower than average quality shaker bottle.

Drinks stay nice and cold for a long time, if you plan on mixing protein powder with it I suggest buying metal ball.

Muy buen producto
