To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
I have one that is the same make but branded, however, this one is much harder to close have to use all my weight to do it. That being said I would buy it again, its good to drink out of, and have no problem getting it clean after.
Used this a few times for meal replacement shakes. You do have to give a very good shake to blend the powder but think that’s more the consistency of my powder than the cup. The metal ball is very effective. Doesn’t leak at all and has measurements on the side for ease.
Perfect smaller sized shaker. Lightweight but solid plastic. I have been carrying in a packed handbag, full of liquid and not had any problems with leaks and not worried about it breaking. Takes a bit of force to click the lid closed, but that's what you want so you know it's closed firmly. Hook on the top is surprisingly useful as can carry easily on your finger when hands are full.
I love this cup it's so strong, sturdy and durable. I initially bought this to mix up my protien shake with but have since developed an allergy to the powder so I now use my cup for water and take it everywhere with me. I particularly love how I can monitor how much I'm drinking in a day due to the ml measures on the side and I love that is does not leak at all.
