This cup is amazing! I love that it works as a shaker for my protein drinks but does not make a ton of noise. It is easy to clean. I have not put it in the dishwasher. I had wash it nightly. On the inside of the cup, it has measurements for water, so you know just how much water you are adding and do not need a separate measuring cup. It keeps my drinks cold and does not leak when carrying, shaking or drinking out of it. I love that the insulation keeps it from getting condensation on the outside and from my drink getting warm quick. I went with the blue cup because it had faster delivery; however, it arrived a day late. No issue with delivery though. The blue color is really nice. The cup seems durable, but the lid where you drink from is a little difficult to open. I believe that is to prevent any leakage when shaking though. Overall happy with this purchase.

I seriously use this shaker every single day and I’m obsessed with it. The quality feels so much better than the cheap plastic shakers I’ve used before. It keeps my drinks cold for HOURS, doesn’t leave that weird smell behind, and mixes my protein shakes perfectly without clumps. I also love that it’s stainless steel because it feels way more durable and easy to clean. The size is perfect for everyday use, whether I’m at work, the gym, or just at home trying to get my water and protein in. The lid seals really well too — no leaking in my bag at all. It’s one of those products I didn’t realize I’d use this much until I bought it. Definitely worth the money in my opinion!

I love this thing. I use it all day every day at work for my drinks, whether it’s just water or it’s energy drinks like gfuel or gamersups. It keeps water cold for quite a while. I will say the lid doesn’t seem to insulate as well as a brand like Yeti but this is far cheaper and great quality still. I’ve dropped it a couple times and no issues so it seems durable to me. I haven’t deal with any leaks, it seals well. The size is perfect for my use too and having the handle on top makes it easy to carry when I have my arms full on my way to my work truck

I needed a new shaker bottle because I wanted to move away from the plastic ones. While this bottle has a plastic top, since it's a silent shaker (the shaker part is a wire screen that sits in the cup) I don't have to worry about scratching plastic particles into my drink.

This bottle is leak proof with a caveat. As long as the cup's snap top lid that seals the sipping area doesn't rub against anything in your bag, you're fine. However, if you toss the bottle into a bag with things that might snag on the snap lid, you really risk the lid popping open and have your drink spilled everywhere.

The insulation for the cup is decent, but doesn't last as long as a bottle that is vacuum sealed like an Owala or Hydroflask bottle. It's summer time now and I like to keep a cold drink by my bedside in case I wake up from it being too hot. With two jumbo ice cubes, the coldness lasts through to the morning. In the morning, the ice is fully melted, but the drink is still out-of-the-fridge cold, so that's good enough for me. If I used my vacuum sealed bottles, the ice would still be rattling around. So that's the comparison.

Overall, great build. Perfect for mixing all the different drinks I make for trips to the gym.

So far so good. It really does keep my protein shake cold while I'm drinking it. I hate drinking warmed protein shake. It mixed very well and best of all NO Leaks...as promised. I like the feel of this it feel sturdy and looks good. It has fitzsitz in all cup holders that I own wonderfully. The flip top spout cover can be a little tough to open at times but I appreciate that as I know that it's sealed properly, I've quickly adjusted myself to open it smoothly and as intended.

No complaints from a daily cold brew coffee drinker. The large size holds plenty of volume, the insulation does its job, and the shaker grate conveniently keeps ice separated. The handle is great for on-the-go and it's great that it's dishwasher safe. It's top opening easily accommodates a straw if desired.

Best cup I've ever had. Mixes well with no clumps. Stays cold longer. And super easy to clean either in dishwasher or by hand. Also not a ton of silicone internal pieces. Other cups I've had have silicone pieces that tend to pick up the smells of old shakes and milk. I lost this cup for a few weeks and it was dirty. When I found it, it was disgusting. One run through the dishwasher and it was good as new with no residual smells.

I was looking for something that wouldn't drive me crazy with a ball bouncing around. This mixes silently so it's not obnoxious while traveling or while at the office. The outside texture feels great, the carrying handle is perfect and the flip-top and lid are secure and leak proof. It's easily washable and mixes my shakes really well. The color is gorgeous well. The two minor "could be better" things are really my personal preference - a) I wish the flip-top went back a little further so it wasn't in my face. And b) I wish the I side lines had an 8 oz marker so that I didn't have to eyeball between 6 and 10. All of my shakes take 8 oz and I find it odd that something so standard isn't one of the premade markings on the inside of the tumbler. That said, it keeps it cold, it fits in my cup holder, and it checks every other box for me.

I was so excited to use this product but was completely disappointed when it arrived dirty with condensation in the bottle. There were chips on the handle, scratches all over the base and the rubber bit was dirty all over.

I am very picky when it comes to water bottles and shakers. This one hit almost all of my ridiculous expectations! No noise when shaking it, check! No sweating on the outside of the cup, check! No clanking noise when putting it down on a hard surface, check! Leak-proof, check! I wish it had a straw option; that is the only thing missing from my "wants" in a shaker. Do not hesitate to purchase this!

Pretty good, albeit slightly expensive due to import costs. I love how everything is either stainless steel, glass, or fubber. No plastic involved on the inside anywhere. Doesn't smell either though it takes a while to dry.

It’s good! Recommend. Useful and keeps things cool overnight.

Genial!! Me encantó que es de buena capacidad pero por la forma y tamaño no es estorboso. Trae medidores internos, el espiral es muy bueno para deshacer los grumos de la proteína y es súper fácil de lavar, la tapa es totalmente lisa por dentro, lo que facilita la limpieza porque no hay espacios de difícil acceso por donde se oculten residuos. Recomendable lavar la tapa con esponja suave para no rayar el acrílico, que por cierto, es de bastante buen grosor y práctico para que observes cuánta bebida tienes. Mantiene genial la temperatura y la asa es bastante resistente y práctica. En general es un muy buen producto. Cero fugas. La base de goma totalmente antideslizante. Lo recomiendo👍🏻
