Convenience Nutrition Stacker Bottle Black

Right out of the box, the first thing I noticed is that the edges are sharp. You can easily get cuts when you wash them or tighten the stacks. I had to manually trim the edges using a cutter.I bought this for my protein powder which is very fine powdery particles. If you will just open the side opening without shaking the powder back, you will create a mess. When you pour the powder to your protein shaker quickly no matter how big your shaker is, you will create a mess. I haven't wash my stacker bottle yet but I'm guessing it wouldn't be easy too.I still gave it 3 stars but would not recommend it to others.

I used these when doing a cleanse that required two scoops of a powder supplement 3x a day and various vitamins and pills 3x a day. I liked that you could use all three together (keeping the powder together with the specific pills that go with that dose of powder), or you could separate them and use 1 or 2, or 3. I also like how easy they are to clean, that they have an "easy pour" spout on the front of each section, and that the pill holder has separations for ease of keeping pills straight.

I bought this so I can keep it in my backpack during school. The containers is really big. Has way more capacity than what I need and takes too much room. Other than that it seems solid and doesn't leak

It would be nice if they came with lids for all three sections, as you don't always finish all three at the same time. However, good deal for the price.

I bought this stacker and it carries everything I need in one container! I use it for my protein powder, and my vitamins. I like the vitamin holder underneath each lid! I will get this for a gift!

It wasn't that good. You can't detach the Stacker bottles and use it individually because the bottom two bottles doesn't have its own cap. I used it to store my protein powder and most of the time, when I open it, some of the powder spills out so it's not really that secure.

Makes life easier when leaving the gym or returning home to have you protein ready to pour.

Great product, well put together, perfect for taking a day's worth of supplements with you.
