Easy to use. Stays sealed. Stays charged.
Size: 12 Combo Travel Size
I had previously bought packing bags in a store — the kind the you had to seal and then roll/squish the air out of one end of the bag. It really took 2 people to remove most of the air. I took them to Mexico, and they were just OK. I switched to these vacuum bags before our family ski trip. What a great purchase! This set includes multiple sizes, which worked well for both everyday clothes and bulkier cold-weather gear. They also fit well inside different size suitcases. One tip: Fill the bag, seal it shut, squish some air out, but then suck the final air out with the bag already inside your suitcase. You can "massage" the clothes and guide how the bag flattens out for a really efficient use of your suitcase space. The organization you can achieve is really impressive. The bag material and valve is tough enough to not allow any air leaks. The red "glides" they provide make sure the seal is solid and easy to achieve. And the system is simple enough that I suspect that elementary kids or people with lower dexterity could operate it (my teens certainly had no issues packing themselves). After returning home, I folded all the bag along their original fold lines, charged up the "sucky thing" (which still held 75% of it's charge after being used at least 20 times), and tucked it all neatly in our travel drawer, ready for our international trip next month. Great value. High quality. I'd even go so far as to say they're fun to use.

Travel bags
Size: 12 Combo Travel Size
Perfect packing bags. I’m using them for a trip to Alaska. The pump works easily . I tested them out and the air retention is perfect.? They are not too thick and will not take up space. The material seems like it will hold up without ripping. I will be using them often. They come in different sizes which work perfectly with different items.

These are a travel must!
Size: 15 Combo Travel Size
We recently took a trip to Japan and South Korea with our 3 kids, and needed to bring all their clothes for 2 weeks, with as few suitcases as possible. These bags were a life saver! We were able to fit so much more stuff in our suitcases with these bags. I don’t know how we would have brought everything without them. We would have had to bring at least one, probably two suitcases more. Easy to use - the vacuum is compact so you can bring it with you, but super powerful and works quickly. Remember to charge it after you use it for when you pack back up. But, you can manually push out the air as well if you’re in a pinch.

More pros than cons, very convenient, but durability is an issue.
Size: 15 Combo Travel Size
Pros: I think that this is a good product. I've had it for several weeks and travel every week for work. It's a good design and the vacuum pump is ergonomic and reliable, in my experience. Charges relatively quickly at home and I'm not sure how long the charge lasts, because it's convenient with a USB-C port, so I charged whenever the charge got to 3 bars. My experience is that dress shirts maintain the pressing if folded and packed neatly. They're creased, but hang them in the hotel bathroom and the steam from a shower loosens the wrinkles nicely. Cons: durability. The bags are pretty thin and after 3 or 4 trips the seal in the bag(s) can become compromised. I suspect the leaks are tiny and in the actual bag vs. the seal. With regular use, this was in only two of the fifteen bags. The double zip lock is really durable. FOR CAMPING: they were great for motorcycle camping, however the durability became an issue. I was camping along a lake and took some care with the bags, but admittedly was a little harder on them than I could have been. I took extra bags just in case, and am glad I did. Three of the 6 bags I took slowly lost the vacuum. If you're using them for camping, pack extras. They're inexpensive enough to continue to buy replacements periodically and you do get a lot. TIPS: pack the vacuum in the suitcase with the bags. Pack the bags with a complete outfit for each day. The temptation is to pack shirts in one bag, socks/underwear in the other, etc. It's more difficult to repack dirty clothes that way, but if you have each day in its own bag you just use each one for a dirty laundry bag.
