I am very satisfied with these shakers. The lid is tight enough so I can toss the best portable protein shaker in my bag without worrying about the swirl shaker leaking onto my stuff. Easy to clean in the dishwasher without any issues. Argos protein shakes are perfect for my car cup holder.
My son and I use the best shake bottles to make protein shakes every day. We didn’t experience any leaks or damage. The seal is tight and won’t leak, but it has to be opened every time. It’s a blessing as well as a curse, as the swirl shaker occasionally splashes on anything on the lid.
I use protein shake bottles to make carnations for my kids breakfast. Works great! I wash it on the top rack of the dishwasher or hand sanitizer. Easy to clean, easy to use, no leakage when shaking the vortex shaker.
I use these to make smoothies in the morning and before exercise. The measuring line helped when I poured 2 cups of almond milk into the measuring line. Add a few scoops of protein powder and shake for a minute or so. Milkshakes are always smooth. There are no gunpowder bombs inside.
When you press hard, the lid clicks when you open it. I really think the swirl shaker has formed a solid seal. So far, I’ve never had a drop of water come out of the lid or from my mouth while shaking.
Besides these, I don’t buy other milkshake bottles. The protein shake blender USB is medium sized. The lid snaps into place *tightly* without spilling. It’s been a while. Now it’s on and off. The cap shows no signs of wear. as tight as new. But I still hand wash the swirl bottle and shake the mug because I’m worried that the high heat of the dishwasher will end up ruining the charm of the MoO blender jar.
