Perfect Size
by Gabriela on 9/16/2019
Perfect size for all your WonderSlim shakes. Not too big or bulky so doesn't take up much space.
Works Great!
by Shawna on 2/27/2017
This came with my kit or I wouldnt have bought it. But it does a Great job of mixing the shakes! The insert does get stuck at times but I can normally get it to pop out by tipping it upside down and thumping it on my palm. Id buy it again for this use.
Loved It!
by Anita on 3/16/2017
This bottle is handy and perfect for the shakes. The included sifter does an excellent job of mixing. I only gave 4 stars because it is hard to see the measurement markings and the sifter doesn't work so well when the liquid is hot. BUT I only know that because I've started mixing my breakfast shake with 8oz of black coffee instead of plain water. OMG. The shakes are yummy on their own but oh baby! The Mocha and Cocomint flavors are AMAZING in coffee. No sugar or creamer needed (and I always piled them in!).
Perfect size, sturdy, mixes well

Looks like they’ve changed the design since some of the other reviews were posted. This came with my order and includes a shaker ball. Works perfectly, no leaks and is a great size for the shakes.
Don't like the insert that helps mix the powder.
by Janny on 10/14/2016
This shaker bottle looked identical to others I have purchased, but I didn't realize this one didn't have the stainless spring ball for mixing. Instead it has an insert in the top of the bottle with openings that are supposed to aid in mixing the powder. The insert works fine for mixing, but it is impossible to remove with out using some kind of tool to pull it out as it seat so tightly in the top of bottle. I find this very annoying and inconvenient.
The bottles leak.
by Allison on 3/27/2018
I got 2 shaker bottles in the 3 Day kits, and both of them leak . They leak on all sides of the top of the bottle. The insert is extremely hard to remove at times. The cover of one of the bottles does not snap shut, so you have to hold it down tightly as you shake. I am disappointed with these bottles.

WonderSlim shaker
by Gloria on 3/31/2019
The shaker was sent in the kit. When shacking the mix with water the liquid would leak out and created a mess. I’m not sure if it should have a rubber ring in the inside to create a solid airtight grip but it doesn’t have one. Therefore I would not recommend the shaker. :(

Nice idea/ poor execution
by jennifer on 9/29/2019
The shaker cup, were it to function as it is meant to, would be ideal. As it is, it is just a littler better than useless. On BOTh shaker cups that I own ( the first one came with my original order and the second one was a replacement for the ineffective first one) the little white lid will not stay snapped shut so you have to hold the lid whilst shaking the cup. And during that procedure, liquid is leaking out the top and dripping everywhere. I will say that customer service offered me a third shaker cup and I declined it as it seems like ALL the cups do this and I don't need THREE non functioning shaker cups in my home.
