BlenderBottle GoStak Twist n' Lock Storage Jars, 4-Piece Starter Pak, Green

This is a great item! As described, you get a 40cc, 60cc, 100cc, and 150cc container as well as a carrying loop that twists on and off just like the containers themselves, allowing for multiple configurations.The GoStak looks as if it's made out of glass because it is so clear (which I really like), but is actually a hard - yet lightweight - plastic. That's another great feature about this: it isn't heavy at all and is easily transported. It is also very easy to disassemble and re-stack the containers. As soon as I received this item, I couldn't help but play around with stacking them in different arrangements for a good 10 minutes. It also feels very secure once you lock the containers in place. It is highly likely that once you have one, you will want to get more as you think of more things to put in these containers. This would also make a great simple gift, as there are so many uses for these! Currently using the 40cc for creatine/glutamine pills, the 60cc for C4 pre-workout powder, the 100cc for BCAA powder, and the 150cc for whey protein.

Not going to lie, I was pretty taken aback with the size of the containers. I figured the stack was standard water bottle thickness and almost sent it back when I saw how tiny the compartments were. Even the biggest compartment is only slightly taller than baby carrots (and can only fit about 8 regular sized ones), or a little over a half cup of liquid. BUT, I ended up keeping these because I got them to force myself to eat healthier. Tiny though they may seem, I realized that these are really what ACTUAL portion sizes look like (not the overinflated American-sized kind). The large container is perfectly portioned for a serving of cottage cheese, and the top containers are great for a portion of nuts. The second to largest container is big enough for one scoop of protein powder. PLUS, the containers can be mixed and matched to suit your individual needs. If you want five big containers, go for it! Heck, you could probably string 10 of them together if you felt like it. They're made well enough where it would totally be doable. I would caution, though, that if you're looking to transport any portion of last night's leftovers in them, it's not going to work out so hot. Just stick to regular tupperware if that's the case.

I was looking for something that was easy to carry around, sizable and expandable (I have 2 of these) and easy to transfer powders to/from. These fit the bill almost perfectly. They are a tad hard to get the powder into from some of my proteins due to the smaller circumference (they fit completely inside a Blender Bottle) but other than that they are perfect. They are good quality (lids are not as sturdy as I would prefer but overall very good quality product). I will update my review if anything changes but so far these plus my Blender Bottle is my go to. They have won out over the Core 150, Smart Shaker v2, Spider Shaker and those crappy shakers you get for free some places. 5 Stars for a product that finally ended my search for the solution to my protein and supplement transportation needs.

Love, Love, Love these gostack jars!! I put my daily vitamins, meal replacement/protein powders, and my occasional almonds or other snacks in them. They're super handy! I throw them together and put them in my 28ounce blender bottle and go. Its waaaaaay better than carrying around those huge jars or containers of your meal replacement/protein powders. I'm really fond of the portablitly and convenience of these jars, they definitely make things a lot easier. They are also very sturdy little jars, don't worry if you drop them, they don't break easily. Im definitely buying at least one more starter pack to have as an extra.

It's quite a bit smaller than I thought it was going to be. In my mind, I had compared it to the Twist n' Lock expansion for the Twist n' Lock shaker bottle. This is my fault, as the sizes of these are clearly defined as 150cc, 100cc, 60cc and 40cc. I actually really like them for some things, but not for others. The 100cc and 150cc cups are good for storing/carrying protein powders/preworkout powders as well as small snack items like cereal, baby carrots and the like. They are NOT wide mouth cups, though, so getting the protein powder into them either requires a small scoop OR a funnel...or very steady hands. I keep a stash of ibuprofen in the 40cc cup. The 60cc cup is just an awkward size for the stuff I like to carry but you could probably use it for dipping sauces if you use the larger ones for veggies. I do like that you can buy expansions to this. I may buy the 150cc 2-pack and possibly the 100cc 3-pack as well. Sturdy construction, really a great idea. I would like to see them make a slightly larger version of this exact thing. I think the size of the cups that are for the shaker bottle would offer more utility but I like this design better (this type of clear plastic, carrying handle, etc.). Idealy, in my world, I would like to see them use this product design (clear plastic, carrying handle, etc.) and make it with a slightly larger circumference (not as wide as the shaker bottle expansion) and make it in the sizes of the expansion (250cc/150cc/100cc/50cc), I would be happy. Still, though, it's a great product (in my humble opinion). Just be aware that it is smaller than you think it is.

This may be the best thing I have every purchase. I take supplements almost daily to ensure I stay in tip top shape. I use this daily as well, the top part for pills, the second part for BCAAs, the third for pre workout and the 4th part for protein. I don't know what I would do without this. It makes it so much easier to transport all of those things instead having to carry each individual tub around with me. I plan to buy more in the future that way I can preemptively plan out a few days in advance instead of having to constantly remember to fill them up daily. I think they would be good also for snacks for little kids that like things like gummies or cheerios. Would be the perfect way to transport last minute snacks to the park or out on a shopping trip!

I've been through numerous snack containers for my kids, this one is love! *See through so you know what's in it. *Variety of sizes for appropriate portions. *Variety of colors to identify which Go Stak belongs to which child. *Still functional when your snack carrying days are over. *Eliminates the need for plastic bags or individually packaged snacks. Mother Earth loves the Go Stak. Be prepared for numerous compliments and questions of how one may obtain such an incredible storage device. Get this, pack it up, put it in the bottle holder of your diaper bag... and give yourself a parental high five! *I have two girls and ordered 2 starter packs + 2 extra 150cc containers.

Coolest snack gadget Ive every purchased. Every time I take this out of my bag to snack, I get asked, "That's really cool- where did you get it"! I love how I can arrange the cups in the order I want or that I can bring/use as many of the cups as I want. I also love that I can clip it onto my bag, carry in my purse, and have a variety of snacks throughout the day. The cups are easy to open and easy to attach to one another. And they come in Great colors!
