Smartshake Slim 4-Pack Protein Shaker Bottle 400 ml | 13.5 oz – Storage Included - Leakproof Screw-on Lid - BPA Free – Unisex - Black, White, Stormy Gray, Cotton pink

Great little cups. I’ve shaken my my way through 30 pounds of weight loss with these little cups. Perfect for Slimfast and similar mixes. Only complaint is that the plastic smells a little funny. Might be off putting to some, but doesn’t seem to add any odd flavors to the contents. Otherwise, it’s tough plastic that doesn’t leak a drop if it’s closed properly. The snap closure is a little tight, but once you get it, it’s perfectly sealed. Wouldn’t mind having larger capacity versions of these for various things. For the price, a very solid purchase.

My fiance and I recently started a protein powder liquid diet where each packet of powder requires 8 oz. of water. After a lot of shaker bottle research on Amazon, I chose these (13.5 oz size) and I'm glad I did. The size of the bottle is perfect, not too large and not too small. But the very best part is the mixing "net" that snaps into the lid. There's no messy metal or plastic ball to deal with that is typically loud and difficult to clean. The "net" quickly & thoroughly mixes the powder and water together and is easy to clean. My only wish is that the flip-top spout guard had a clasp on it to make sure it stays closed if needed. Overall one of my better Amazon finds.

I can't comment on the durability (yet), but the size is perfect for my daily greens shake and the screen works well so the powder dissolves. The tops are tight and leakproof. Recommend.

These are decent and a great price, but I much prefer the shaker ball. The "mixer net" does not mix as well and powders get caught up in it and clump. I like the idea of never losing the shaker ball, but one of these mixer nets keeps falling off when I open the bottle, so that defeats the purpose. If I remove the net and just shake a mix up in the bottle, clumped up powder gets stuck in the groove where the net goes. Also, the flip top on one does not snap in place securely, so that I feel like I have to hold it down when shaking just to be sure it doesn't make a mess. They're a good size, work reasonably well, and the screw on top stays securely, but I have moved some of my old shaker balls over to these for better mixing.

I use one for myself to have protein shakes and I love that it doesn’t have the little metal balls to mix my powder up, the insert that goes at the top mixes everything up as I shake it. I use another for my newborn to mix up a days worth of formula for him and it also mixes perfectly as well and when I pour it out the insert breaks up bubbles. I have no issue with the lid seal, I haven’t experienced any leaks. The colors are true to the photo in the image. For the price, it’s a great value to get 3 for the price of most cost for 1. The product itself feels like great quality. I’ve dropped them a couple times and haven’t had any crack or get damaged. They are definitely durable.

They are okay, the only issue I have is that the shakers don’t have metal blender balls to mix. The mixer is plastic screen inserts that are difficult to insert in the cup. I kept them because the price is good. I replaced the mixer inserts with ones from my old shakers. There durable, leak proof, and the perfect size.

I got these on prime day sale. Love love love!!! Need I say more? No leak, wash well and very durable

OMG, I absolutely love this shaker set! This is my first time ordering shakers, and I'm so impressed with the quality. The tunnel size, storage, and overall design are perfect. I'll definitely be ordering more in the future!

Exactly as described

Son de un plastico muy delgado, dos se me han estrellado y roto en su totalidad, en caidas menores a un metro en el gimnasio, no los recomiendo.

Besonders begeistert mich das smarte Aufbewahrungsfach – perfekt für Supplements, Snacks oder sogar Schlüssel, wenn ich im Fitnessstudio bin. Die 150 ml Kapazität des Fachs ist genau richtig!Das Material ist hochwertig, und es gibt keine Probleme mit Leckagen dank des sicher verschließbaren Schraubdeckels. Das Design der Flasche ist super durchdacht – von der breiten Öffnung, die die Reinigung einfach macht, bis hin zum leisen, klumpenfreien Mischen durch das spezielle Netz im Inneren. Keine nervigen Rasselgeräusche und immer ein perfekt gemischter Shake.Ein weiterer großer Pluspunkt: Die Flasche ist BPA-, DEHP- und BPS-frei, was mir ein gutes Gefühl gibt, wenn ich sie täglich benutze. Außerdem ist sie mikrowellen-, gefrier- und spülmaschinenfest, was die Handhabung im Alltag sehr erleichtert.Ich kann die Smartshake O2GO ONE jedem empfehlen, der eine zuverlässige, langlebige und durchdachte Shaker-Flasche sucht. Sie hält definitiv, was sie verspricht, und ist ihr Geld wert!

Al last , no more metal whisk ball, or rattling sound. Use these at work. They're brilliant. Mix powers well. And completely leak proof. I even use one to take milk to work for coffees. All round great quality and value

Au top pour le prix ! Se nettoie bien et ne garde pas trop l'odeur du contenu contrairement à d'autres.
