ZOORON Protein Shaker Bottle, 100% BPA Free Gym Bottle Shaker 16oz Shaker Cup with Storage Great for Powder and Capsule Organizer

The shaker spring does not stay in place unless you are doing very calculated movements... I dont have time for that. It does get all the chunks out though, so that's awesome. The bottom is odd to screw on and off since it locks up if you try to screw if off with any form of force. It doesnt stay screwed on while in my work machine.... found that out the hard way with powder going everywhere this morning.

Like the functionality of the product and the design but feels a little cheap but still really enjoy it daily.

These are very good and have places to store things when you are out. Screwing on the lid can be a little challenging but I still like it

The lid pops open easily and the spring inside moves around. It's not a bad shaker and having the different parts is good for carrying my protein or small snacks. I just wish the mouth piece stayed closed better as well as the spring staying in place.

Este producto es muy defectuoso,la pintura se desprende,te queda atascado la base de abajo.. en pocas palabras, no sirve!

Great product, I would buy again

Son muy mala calidad en la primera lavada ya no tenía ninguna letra.la tapa no sierra bien.la pieza para mezclar se caía cada momento.

Good shaker the mixer is just ok I like the ball shaker better but this is still a good product
