BlenderBottle GoStak 100cc 3Pak - Black Color Black Style: 100cc 3-Pak, Model: C00315

I bought two sets (3 in each) of these in the 100cc size. Each container perfectly fits one scoop of my protein powder. It was a little messy to transfer the powder from the scoop to the container, even with a funnel. So, I found that just using the container to scoop out the powder works best. The lids seal tightly enough that you can just rinse and wipe the container after you fill it without having to worry about water intruding when you rinse. I just traveled using these and it was great. All six of my containers nicely attached to each other and it was very easy to just pack the cylinder in my suitcase. They never leaked, came apart, or broke; it worked perfectly. This is a nice travel solution for packing the protein that worked quite well for me. I am very pleased with this purchase and highly recommend.

These are great quality and fit in the Dometic fridge door. They’re leak proof and the hard foodsafe plastic doesn’t absorb odors. I use them to keep condiments in the van without using too much space.

These are great! No leaks and seals tight to keep my food fresh! They are so easy to clean and easy to use, and the small size is great for travel, especially light travel.

These are great for protein powder when going to the gym. Great quality, compact in size, and durable. Thick plastic that you don't have to worry about breaking when it gets dropped. Holds the exact portions of what you need.

The idea behind locking and stacking bottles is great. I take a lot of lunches and snacks to go, sometimes a breakfast too. What i was hoping for is replacing the 2 - 3 cheap-o Rubbermaid containers I get from the grocery store. This helps, but doesn't quite take the cake just yet. First off the downside is the sizing. In the picture it looks like you can fit all kinds of goodness in here. Carrots and hummus, protein powders, granola, vitamins, nuts, fruit cocktail, pink popcorn, you name it. It's true to an extent, but it doesn't really match viable portion sizes to carry me through the workday. The top smallest container fits vitamins or pill supplements really. You can fit 2 Tbsp of hummus but a bunch would get stuck to the top, its best suited for the 2nd container. The 3rd container is 100cc's which should be about 1/2 cup, but I could realistically only fit about a 1/3 cup of walnut halves in there. The issue with Baby carrots is you have to stack them vertically, and pick the smallest ones to shove in there meticulous, and even then you can only get about 8 total baby carrots with a tight fit. Good luck getting them out though. The largest container is 150cc which is just under a 2/3 cup. However, for standard protein powder (right now I have muscle milk), 2 scoops is about 70g, which does not fit. You can do about a scoop and a half. The upsides-- The lid screws on one way, but the stack & locks can screw together both clockwise and counter-clockwise, which makes unscrewed over-tightened lids a cinch. The hard plastic is more thicker than a blender bottle, but I wouldn't put liquid in these, maybe yogurts at best. Cleaning is simple, top rack in the dish washer, or by hand, but somehow even after drying it retains a spot or two of moisture which I notice with the protein powders. The handle at the top with the starter kit, is super handy to pull in and out of a bag. Overall a decent purchase, but it was hard to visualize the sizes until I actually had the thing.

Absolutely love the versatility of these little gems! I use them for my morning powders that go into my drink! Super clean, efficient and the perfect size! You can take them traveling, put buttons or small items in them, or whatever you need! Clean and organized! JUST PEFECT! Update with PHOTOS! I think they are AWESOME! I use them for several different powders... It does depend on the type of powder though as to if it will stick or not. For example, I use one set for my 'morning' powder drink which includes a fiber powder and 'Active You' and these stacks are bone dry. Work extremely well and super convenient for me as I just grab and go. My second set I use for supplement powders including Cocoa for smoothies and the powders have more wetness to them. I will be leaving a new review for them online as this link won't let me include photos. So, bottom line, the drier your powders are, the less residue that will be left behind. I love them so much and actually have taken them on trips and they are so convenient!

I was initially going to just write a review to the effect that it does what it’s supposed to do, but that would be short-selling this product… There are likely less expensive ways to store stacks of powders. What’s really amazing is how well the containers stay shut — and how they somehow can be unscrewed, regardless of how tightly they are closed, when they’re hooked onto the container above. I travel a lot and have had more spilled powders than I can count - so I am grateful to have found something that actually stays closed even when bounced around in my bags. My only criticism is that there are only a few sizes available as add-ons and – but it’s worked fine for my needs.

Very useful container for trip if you wanna travel with your protein and creatine

I was going through the reviews and just noticed one by a Drew M. I don’t know what you’re talking about, Drew, but these are some very high-quality products. They seal very well, are made of incredibly durable, even noticeably weighty and dense, BPA free plastic. They stack together like a dream and, as hard as they can be to open WHEN YOU DO IT WRONG, they’re designed to open using the bottom of another bottle, which works beautifully. Maybe you forgot to read the only instruction card it comes with. As far as cleaning goes, this was very easy as well. I bought them because of how easy they are to clean, mix and match sizes, and how well they’ve been reportedly holding up for people. The “offensively small” containers are for people with some amount of dexterity, sure, and you need to have something small enough that you care about carrying with you before you’ll appreciate them, but not being capable of opening and cleaning these is not something you should be coming to the review section of this product for, it’s something you should be making an appointment about. I’ve been looking for something to meet my extraordinarily specific criteria for a long long time and these really are it. I ordered two starter packs and can’t wait to get more.

I bought these to use as snack boxes for my kids. They're a lot smaller than what I imagined they would be. I have to take 2 sets of 4 + a lunch box to have enough for a 3 and 4.5 year old. I'm not going to rate them low because of it as it's my mistake. It clearly says "blender bottle". They work fine and they seal well.

I needed portion control after WLS. This container is easy to clean and is secure enough to put in my bag. Getting another for my daughters snacks.

il est solide il tienne bien emboîter le seule soucis il sont assez petit mais rien de méchant juste prévoir d'aller sur le site pour acheter de plus grande Gostack

Ho comprato questo set per il trasporto di proteine, vitamine ed aminoacidi. Non mi sarei mai aspettato una qualità così alta, sono stupito! Oltre ad essere di ottima fattura sono anche super comodi, soprattutto grazie alla possibilità di poterli incastrare l'uno con l'altro! Per far comprendere le dimensioni, questo da 100ml contiene perfettamente 30gr di proteine in polvere! Spedizione amazon impeccabile!
