I had a friend recommend packing cubes when she heard my husband, two year old, and I were going to Europe for two weeks and staying at 6 different hotels. I looked at a variety of options when typing in "packing cube" and finally decided on the Shacke Pak brand and Bago brand.I chose the Shacke Pak brand because I liked that it offered four different sizes and it being my first time purchasing these I wasn't exactly sure what sizes to get. I also liked that with Shacke Pak it came with a laundry bag, which definitely came in handy, because there were times we got rained on all day and with our full packed trip and we didn't have time to find a washer and dryer, so it was nice to separate some of our dirty clothes in the laundry bag. I also really liked the biggest size that it came with and was able to pack almost all of my clothes in just the biggest size for a two week trip!The reason I chose the Bago brand was because I liked that you had the option to choose all of one color or two different colors. I also liked that it came with 6 organizer bags which I used to put our liquids in, incase they leaked. The organizer bags are a lot thicker than your regular ziplock bag, which is what I have usually used, so these will last a lot longer, and there are multiple sizes, so I could separate our toothbrushes and paste in one and soaps and lotions, etc. in another. I also used them to put chargers and adapters in, so they were all together.Overall, between the two brands, as far as durability goes, I honestly didn't notice much of a difference. They are both really thin and light, so they don't take up any extra room in your suitcase! We had them packed full, (especially on our way home) and we didn't have any problems with them! They served their purpose and if or when I need more I will definitely purchase again! Shake Pak was a little more expensive than Bago. I believe I paid $21.99 for Bago and $29.99 for Shacke Pak. I really like the biggest size that came with Shacke Pak, the Bago ones I purchased only offered two sizes that were the two middle sizes offered from this Shacke Pak purchase.Also, I should mention, I purchased brands different from what my friend recommended because these were half the price and honestly, I loved both of them and thought they were very durable. I can't say enough good things about packing bags and I don't know how I ever lived without them! We took one big suitcase, because with a toddler, we needed one person to have free hands when traveling between hotels. In our big suitcase, we packed all four of the Bago bags, and then the 3 biggest Shacke Pak bags. So, that's 7 packing bags, stuffed clear full in one big suitcase for a two week trip across Europe. We each used two bags, and then used one bag for liquids and accessories like chargers. And on our way home, we had the laundry bag half way full, with the 7 bags clear full and we were still able to zip our suitcase up! Also, each bag comes with a handle, and we packed them so the handles were on top, so we could grab our bag out of the suitcase by the handle!On our way across Europe we picked up many souvenirs that we rolled up with our clothes, so we were able to fit even more stuff in our suitcase! These were so convenient too, because each of us had a different color, so when we needed something, rather than making a mess of the whole suitcase trying to find it, we would grab the color of bag for that person! Prior to this, I would end up repacking the suitcase every time we moved locations, so, if you are debating whether or not to get Packing Bags, I would recommend you make the purchase! These are a time saver and space saver! It is so convenient to just grab your bag and put it in the dresser at the hotel, rather than all of your clothes, and they beat repacking your suitcase every time you move locations, or even just when you're leaving to go home.Overall, the Shacke Pak brand was great, we liked the variety of sizes (especially the biggest size) and that it came with a laundry bag. Lastly, if you haven't purchased or used Packing Bags before, I would highly recommend them! They are amazing!
