Title: careful, it may leak
Review: It has a terrible desing flaw. I use it to mix and carry protein shakes. I put the powder in, put the cap on and when i am ready put the milk or water, shake and drink. Too good to be rated 2 stars, isn't it? well that was the good.The bad is: the tread that hold the cap is inside the conteiner so when you mix, the mixture go thru the tread (it doesn't look nice), and it's supposed to be hold in by a clear tiny silicon-like band that is attached to the cap. If you tighten the cap too much, the band will be squeezed out of position and leak. If you do not tighten it enough the band won't seal and leak.Another thing, maybe not as important as the above, is that it is little uncomfortable to drink directly from the bottle, the lid keep closing everytime.So before you make your decision analize carefully. Despite all that.... It mixes, when you get it right(until the band break) and spray eventually
Is the review positive or negative?
