-6 PACK- 28 oz Shaker Cups for Protein Shakes - 6x Wire Whisk | Leak Proof Large Shaker Bottles for Protein Mixes | BPA-Free Protein Shaker Bottle | Protein Cups Shaker

There are no silicone seals, but they aren’t needed. The plastic is molded so precisely that everything locks tight. Once the lid screws on, it is airtight. Everything is so tight fitting that it’s even hard to get the drinking part to open without effort. It could be that these are new and that they will wear down with time, but so far, so good. I like that you can see through the container. I can tell if I need to mix a little more or if it needs to be swished around again if anything settles at the bottom. I also like that the set has different colors. It helps to break up the monotony of using the same thing all the time. For those who like to mix bases and lids, they can have a lot of fun with it. I’m a purist. The bases and lids have to match. Having the different colors will allow someone to keep track if they use more than one mix. I also like that this set has more than two in the set. It allows me to use one and still have plenty left over for my family if someone needs one for the day. Having the measurements on the side is helpful to gauge how much liquid I’m taking in, and the measurement gauges are recessed into the side, creating perfect grooves for putting your fingers. The measurement lines also provide some grip while shaking. For getting six of them, the value is there. The plastic is thick and sturdy. It isn't fancy, but it will get the job done.

I like having a good supply of these things cause I drink a lot of shakes, smoothies and supplement drinks over a day. I can reuse bottles often, but honestly it's much easier to just grab a new one and toss the used ones in the dishwasher. This is a pretty good value on a 6 pack of vibrantly colored bottles. Nothing about them design-wise is incredibly noteworthy. Nothing innovative at least. They ARE good quality though. No misfit lids or leakage. The plastic is thick and durable. Semi-translucent design lets you see the level of your drink which in combination with the measurement lines on the side makes for easy dosing. The stainless steel mixer ball does a good job of breaking up clumps, though results are going to vary depending on thickness of the drink and the nature of the powder. But at worst, it just takes a little more time shaking it up to incorporate it. So I do recommend it and it's a great option for those getting their first several bottles or someone looking to add or rotate new ones into their collection.

The weird shape of the blender thing often gets stuck in the bottom of the cup. Other than that, they seal tightly and the mouth is nice and wide for drinking.

I love the color variety these cups have. I am able to leave some at work and some at home now with this large pack. Each cup comes with its on whisk, so I don’t have to worry about losing one and not having one for another cup. With the lid closed, I have not had any liquids spill out during my shakes so that is great. These are easy to hand wash and throw in the dishwasher also.

I've had leaky shaker bottles before, and they are an absolute mess plus they can be a nightmare to clean; luckily, these have a tight seal and they are a breeze to wash. I was impressed by the strength of the bottles and overall quality of this product. The colors are vivid and attractive. I actually think this could be a great gift for friends on an athletic team or league, so everyone could have their own colorful bottle to use post-workout if desired. The cups stack nicely and the mouthpiece is relatively easy to open and use, especially compared to some similar bottles I've used in the past that require a bit of finagling to pry open the drinking spout. This is a great value, and it's a practical, user-friendly, attractive, and affordable way to blend some shakes or smoothies while maintaining an active, mobile lifestyle. The bottles also travel well; I brought one on a cross-country trip and it worked seamlessly. Highly recommend.

This is a fantastic value for the money!! Six shakers for 20 bucks basically?! Heck yes it’s wonderful!!! I am not a boujee, namebrand type of girl though, so I just needed cheap and functional and this definitely did that!!! Love it!

These Velomix shakers offer good value and are an affordable alternative to other shaker bottles costing 3-4 times more. These are certainly not as nice as shaker bottles offered by some other well known brands, they perform very well and get the job done. At the end of the day, it's a hard deal to beat given the price point and I have been very happy with these so far.

These are usable and inexpensive shaker bottles. They have no gaskets, and no insulation, so the lid has to be tightly closed to properly seal, but that also means there’s no gasket to clean or lose.The stainless steel ball works fine.Overall a decent set.
