Alpha Designs Protein Shaker Bottle 750ml - 0.75L Heavy Duty Gym Bottle for Protein Shakes - Leakproof Screw Cap - Clear

No issues of leaking till now for one month usage. If didnt close perfectly then only leaks. Need to put the lead and close is till seal it properly otherwise obviously leak. Loved it !

Good quality and does the job perfectly with enough height in the bottle to facilitate a really good shake and therefore no more lumpy protein. I particularly like the screw cap design in preference to the more standard flip top which always hit me on the face when drinking from the bottle.

It is a nice sturdy shaker, good quality. I have two small issues that worth mentioning. The sealing ring inside it a bit too thin. The shaker does not leak if it is closed properly, but it is easy to screw the top on in a way that moves out the sealing ring from place and then it leaks. The rubber ring could be thicker to solve this issue. The other one is that, it is easy to lose the cap. The cap was fixed to the top on my previous bottles. But probably that is just a "me issue"... :D

Good

I have used quite a few alpha design shakers now as I like the screw cap on the top and the general design of the bottle which makes them easy to clean. However, I simply can not ignore anymore, the fact that they ALL leak from the lid. The bottle lid is completely over engineered, it has a silicone seal inside which one would think could create a perfect seal but it doesn't. When you shake the bottle, liquid escapes. When you drink from the bottle, liquid escapes and drips onto you. It completely defeats the purpose of the bottle. I have shakers that I got for free which are the most basic, cheapest made shaker bottles that don't leak a drop and they don't have any silly over engineered silicone seal inside them. My advice is do not buy. Read the other reviews, I'm not the only one.

This product makes a great water bottle. Just like any closed container. However as a shaker it has a few issues. The main one being the leaking! I can't figure out why but everytime I go to mix up my shakes in here I end up spraying chocolatey brown sticky water all over my office. I've had to adopt a blueroll assisted lid method to assure my colleagues don't look like they just changed the nappy of a very angry baby. I've checked the seal around the lid multiple times when washing the bottle but no awnsers yet. Shame. Another issue I have found is that despite washing the bottle very frequently and with great detail, there is always a fish smell coming from it. Now I don't eat (or drink) fish at all so I'm a little curious about that.

Excellent protein shaker does what it should i highly recommend

does what it says on the tin, perfect for larger shakes

La uso da un bel po' ormai, anche solo con acqua non so sente aroma di plastica, soddisfatto anche per la funzione shaker

Mauvais shaker ! Bouchon non étanche. Pour mélanger ce n'est pas pratique...

Produit de qualité. C’est le 2 éme que je commande.

Tiene una banda plástica para evitar el goteo pero que es muy difícil mantenerla en su sitio haciendo un engorro de limpiar y luego colocar. No lo recomiendo para nada.

Me ha encantado prácticamente en todo. Es un shaker de más capacidad de la estándar (suelen ser de 700, este es de 1000), mezcla perfectamente, tiene tapón con rosca y junta de goma en la tapa. La única pega es que en algunos grifos, al ser de mayor capacidad y más alto, en consecuencia, en algunos lavabos (solo he tenido un problema en uno) no entra para poder rellenarlo de agua. Encantado con la compra, y más en estos días veraniegos donde el calor se nota, 2-3 hielos gordos y a beber!
