Review on 🥤 ShakeSphere Tumbler: Protein Shaker Bottle, 24oz ● Innovative Capsule Shape Mixing ● Hassle-Free Cleanup ● No Blending Ball or Whisk Required ● BPA Free ● Effortlessly Mix & Drink Shakes, Smoothies, and More (Sleek Matte Black) by Kate Love

It was quite expensive for a shaker but with Revain's return policy being so perfect I was willing to return it immediately if it wasn't as described and leave a negative review. I keep it to myself. As soon as it arrived I decided to add the lumpiest cocktail I could imagine to this little guy. 1 scoop of whey protein, 2 tablespoons of psyllium husk! (Competitor #1), 2 tablespoons of PBfit and a banana. I shook it 15 times like in the video, yes absolutely no lumps. Plus, you don't even need a brush to clean it or put it in the dishwasher. For some reason it just washes off almost without a trace. I have 4 cheap wire ball shakers that to use I fill half with water, add a spoonful of whey, fill the other half with water, shake like hell and puff. Anything not to stick together. I then have to let them rinse a little before putting them in the dishwasher, being careful not to let the wire balls get tangled in the frame or with each other. With ShakeSphere this is not required. I only need one too as it's so easy to wash off and use throughout the day. I will still keep one of my wire ball shakers for volume, BCAA and clarity, but for protein I use this one. No lumps - Easy to clean - No wire balls - Reliable build quality - Secure seal (but can't confirm if it's airtight yet) Cons: - Expensive for a shaker (some of my wire balls could just rock freely) - No clear options (maybe has it has something to do with the composition of the plastic used that doesn't allow this) - Small if you need something during exercise to give you extra fluid - The mouth opening is an uncomfortable shape you should almost do a sip with it it doesn't slosh over your mouth - doesn't fit in a standard car cup holder - was a little hard to find on Amazon. I kept looking for a bottle of Shakespeare but it didn't turn up. You need to add that to the keywords and optimize the search (maybe sponsor) for people just looking for a shaker or making the same search error. I would love to see more color options someday, especially transparent ones. Maybe even a bigger and isolated version. My offer, take it. If it doesn't do what it says on the tin, simply ship it back to Revain and discount the product that isn't as described, then choose the UPS option for them to collect it. No stress. However, my prediction is that if you can take $20, you're going to love this thing, and so will I. The biggest complaint is that it shatters if you drop it and isn't dishwasher safe.
