2 Pack 28 oz Shaker Bottles for Protein Mixes, Protein Shaker Bottle with Stainless Steel Whisk Ball, Shaker Cup, Protein Bottle, Protein Shake Bottles

Best shaker cups I’ve used, and I’ve used a LOT of shaker cups!
These cups do not leak. They make a loud snapping sound to let you now when they are fully closed. They are clear enough that you can see any residue on the inside after washing, so you can get back in there and get it. They are wide enough to make cleaning easy. they do not accumulate scent from protein powder. You can see when your powders are properly mixed. These are *almost* perfect, and are better than anything else I’ve tried. They are also affordable!The only change I could suggest is adding OZ. measures on the side would be nice, so users can see how much water has been put in the cup.But these are honestly the best shaker cups I’ve used, and I use both daily, and have done for the past 4 months.Solid product, highly recommend!

Good buy
Excellent

Good for formula
We use these for making and transporting formula and it works really well. Took a star off just because sometimes It’s hard to get the cover part to snap down on the lid. Doesn’t leak!

Won’t stay closed, or open unless you control it.
Garbage. Save your money, or buy a different shaker cup. These don’t stay closed when you shake them. You have to hold the flip lid from opening and spilling your drink everywhere when you shake it. When you drink, the flip lid doesn’t clip to stay in place, so you have to hold it out of the way. There are much better shakers for about the same cost, maybe a dollar more.
