Blender Bottle ProStak System with 22-Ounce and Twist n' Lock Storage C01715

I was actually happy with the purchase a little over a year ago. Good for mixing my protein shake and creatine. I like the extra containers to hold my pills and an extra dose of protein if I happen to forget to refill the main bottle. My big problem is that the lid cracked as shown in the picture. I'm pretty gentle with the bottle while using it, carrying it around and washing it. I was very surprised it cracked. My last one lasted 10 years and I only replaced it because it looked worn. Oh well I guess they just make things so they don't last anymore. Very unfortunate because I really liked the bottle.

This shaker/storage combo is exactly what I needed. It's a great, medium sized shaker with two detachable storage containers and a hidden pill compartment. I place my supergreens mix in one of the containers, throw some vitamins in the pill holder, and screw it all to the underside of the shaker. Now I'm ready to go to work.The pill container hides securely within either of the storage containers lids. There are two different sized storage containers that can be used together (attaching to each other) or separately. There is even a ledge inside of the shaker that allows you to store one storage container inside the shaker and the other can screw to the bottom, so the whole assembly doesn't become too tall.

Fantastic quality! The set comes with the main bottle, lid, and wire mixing ball, then two stackable containers, each with its own lid that stacks into the bottle, one of which contains an additional small container. The additional small container is shallow and divided in half, meant for pills, but I ended up using it for different types of powder (tumeric to add to shakes). So when all stacked together, you can keep a scoop of powder in the bottle, one in each large container, and a half scoop in the small lid container (3.5 total). This makes the bottle excellent for travel. You can carry multiple replacement meals with you. I'm using it right now while on a vacation where our hotel doesn't have great food options. Gives me fuel first thing in the morning so I don't have to feel hungry while we get ready and find a restaurant. It was good for one late night when we were too tired to get food after getting back to our hotel. Super handy and added comfort to our trip. The bottle rinses clean easily (same material as every other blender bottle I've owned). This one comes with a nice hard plastic and rubber coated loop on the top, so you could use a clip or velcro to attach it to a backpack/purse strap. All of the containers and lids screw into each other snug and do not come loose when shaking the bottle. You could easily carry around the bottle with only one or none of the extra containers attached. There are ounce and mL marks on the side wall of the bottle. Overall best bottle I've used for powder shakes. This would make a great gift for any gym goer or traveler who uses shakes.

This blender bottle is ridiculously difficult to open! I got it for my mom to make protein shakes, and to store homemade health supplement capsules and protein powder. But it takes all of my mom's strength to flip the top open, and it's hard for me too. She has to turn the bottle sideways and away from her, press the bottom against her body, and pull the tab up with all her might. The top violently flies open. And this is with an empty bottle! So with any liquid in there, the contents will go flying everywhere.Also, the section that holds capsules is not easy enough to remove. It twists and pulls off in an abrupt way that would send pills flying.Athough I really LOVE the versatile concept of this blender bottle, and its design idea and tough materials, it's not realistic to use for everyone. Maybe after months of use the bottle may become easier and simpler to use. But it's pointless to try to use it until then.

Saw a health nut at work with one of these types of blender containers, so I figured I'd give it a shot so I don't have to use a blender or brisk fork mixing which never works.100% success rate and satisfied. I mix a scooper of my favorite health mix with almond milk and it leaves no residue. For reference, I used Amazing grass green superfood. After drinking it all up, it's pretty much clean already, but put in some warm water, a few brisk shakes and it's nice an clean. I do a second filling of warm water just to be safe.Just make sure you hold your finger over the stopper when shaking it.
