BluePeak Stacker Protein Shaker Bottle 22-Ounce, 2-Pack ProStak. Attachable Storage Containers (100 & 150cc) and Pill Tray Included. BPA Free

The BluePeak bottles exceeded my expectations. Very well-built and a welcome change from the bulky Blender Bottles.I was looking for a slightly larger than 20oz container, and I happened to stumble upon BluePeak. The design is very sleek and quite different from most Amazon listings.The package comes with two containers, one with yellow accessories and another in just black. The yellow bottle is absolutely beautiful!The bottles don't leak, but the containers are not meant to hold liquid.Overall an excellent product, I'll be on the lookout for future colors to come. Fingers crossed for neon green and pink!

Recently got my BluePeak bottles and couldn’t be happier. Having the flexibility to bring my protein powder on the go has been a game changer. Bottles are designed very well and are a lot more versatile than the standard shaker bottles I’ve had in the past. Arrived on time and exactly as advertised. 10/10

Brings two shakers and the shaker is just as great as blender bottles that are more expensive

Got this Shaker because my other ones lost all the pieces. I was very pleased with this shaker, it both provides storage options and mixes my protein powder well. I'm glad I got this one since it was a two pack! I doubt I will need to get another shaker for some time.

This style shaker works really well and I do not have to worry about my protein powder getting stuck in the hallow shaker sphere that is in the old kinds of shakers. Its hard to beat a two pack for the same price as one of my old shakers! I am thinking about buying another before they raise the price.

This product works perfectly, just as advertised. I use the BluePeak Stacker Protein Shaker Bottle heavily and have experienced no issues at all. Very glad I purchased this dependable, high quality bottle.

I bought these shaker bottles to replace 2 old shaker bottles that I've had for 4 or 5 years. I've bought and used countless shaker bottles for my pre and post workout shakes for years and unfortunately this set by far has been the most troublesome for leaking and having the spout cap popping up and not sealing.Last night was the last straw as I was mixing/shaking up my post workout shake and talking to someone when the spout cap popped up and soaked the both of us.

This sat is so flexible. You have two Shaker bottles, and 2 pill containers and two small containers. You can interchange them and connect one or both containers to the bottom of your Shaker bottles. My only complaint is that we've only used them a handful of times and they are already starting to leak a little when shaking. And one of the bottles does not snap close all the way where the drinking spout is. If I hold the lid down tight I can still use it. But I cannot pour water in it to take on the go.
