My favorite blender bottle I own. The colors are beautiful.

Missing one of the jars

I bought the pink one, which came in a sealed plastic bag, but without the bottom storage jar. Now I get to go through the hassle of returning and exchanging. Where I live this is an unpleasant waste of time: I have to take an unreliable bus to the nearest post office, which has limited hours and long lines. Fortunately, I bought it for myself; if it had been a gift, then something I wanted to make someone smile would’ve made them annoyed.

We are sorry to hear about the trouble with your order. We would be happy to look into your shipment and resolve this concern. Please reach out to us at and a representative would be happy to assist you.

I bought this for my boyfriend for his birthday and we are impressed. I get it, it’s “just” a shaker. BUT it’s great quality, the storage is so necessary - especially for someone who travels & the customer service is outstanding. When we got our shaker, I noticed that only one compartment was attached to the bottom so I sent a quick email. I mentioned there was only one compartment but I ordered the one with two. They got back to me in a timely manner and advised that the 2nd compartment is actually stored in the lid for shipping purposes - so just a heads up! Your order isn’t wrong! Anyway, just buy the shaker. It’s worth it.

Love it

I love it! It’s nice having the containers easily attached to the shaker. Super easy to add and change out.
