Over packer approved! GOODBYE checked bag fees!!
Size: 9 Combo Travel Size
These were incredible for our recent flight to Tampa. I’m an overpacker by nature, and we normally have to check at least one bag, but these completely changed that. We were able to fit everything into our carry-ons and backpacks with room to spare, which even saved us from paying a checked bag fee.
The vacuum came already charged, and I still haven’t needed to recharge it, which was a nice bonus. It also comes with a small travel bag to keep the charging cord together, which made it easy to stay organized. The suction is strong and works quickly. I packed one bag completely full and it compressed it down to about half the size.
The bags are durable and easy to seal, even without using the plastic zipper clips. As long as they’re fully sealed, they stay compressed and don’t slowly let air back in. We unpacked everything at the hotel and stored the empty bags in our suitcases, then reused them to pack for the trip home with no issues.
The vacuum isn’t silent, but it’s not overly loud either. I’d compare it to being quieter than a typical hair dryer.
This is such a game changer for travel and saving space. I’ll definitely be using these for every trip.

Extremely well made travel vacuum bags
Size: 9 Combo Travel Size
These are great kits for Travel and storage.
I now have two sets.
The pump works very well. Small enough for carry on.
One very small dislike, There are small clips that slide across the top closer. But nothing to stop them either end. So may fall off.
But I would highly recommend them. 9 out of 10 for me.

Absolutely Perfect?!!
Size: 15 Combo Travel Size, Size: 15 Combo Travel Size
AMAZING!! This made packing soooo easy and such a breeze!! My suitcase was organized & I had everything that I needed for my trip. It has a great suction & comes with several red strips (I’ll call them) to ensure a tight seal before suctioning the air out. The bags comes on several different sizes & hold quite a bit of items in the big bag which held out hoodies & sweatsuits. Vacuum it’s not loud at all. Lightweight but packs power. This is a game changer! Very durable & great quality!! I’d highly recommend this item.

Good Space Savings, but the Bag Zippers don't hold very well
Size: 15 Combo Travel Size
I purchased these Vacbird travel vacuum bags mainly to save space in carry-on luggage and cruise packing, and the overall concept works well. The included rechargeable air pump is compact and convenient for travel, and the compression bags can significantly reduce the amount of space taken up by clothing and soft items when sealed properly.
The bags themselves are easy to fill and compress, and they can definitely help organize luggage more efficiently for longer trips. For bulky clothing like jackets, sweatshirts, or extra layers, the space savings are noticeable. The rechargeable pump is also more convenient than manually rolling air out of the bags repeatedly.
The reason this isn’t a higher rating is the zipper closure quality. The zippers feel much weaker than they should for a product designed around repeated compression and travel handling. Several closures required extra care to avoid separating or leaking air, which reduces confidence in long-term durability. The system works, but the zipper design feels like the weak point and keeps the product from feeling as reliable as it otherwise could be.

Amazing product, and even more AMAZING Customer Care Team!
Color: All Black Premium Gift Box, Size: Z1 Motor + Batteries, Color: All Black Premium Gift Box, Size: Z1 Motor + Batteries
I don't normally write reviews, however I can't not mention the ABSOLUTELY AMAZING Customer Care experience I had with these folks.
But first, In review of the product itself, which is the 'Executive Series Black Milk Frother with Black Holster Stand'. This is my first 'frother' purchase, and I must say I was skeptical at best to try it, but I opted to purchase it anyway because of all the great things the company stands for. I figured, how good could it really work?! Well, as a matter of fact, it worked quite wonderfully! Within just a few seconds / pulses of the frother, you have beautifully frothed contents. It is simple to operate, with one hand, and just the simple push of a button. (I imagine I could even make whipped cream without dragging out a stand mixer.) The batteries, (2 AA - not included), were simple to load. And, there is a battery pull ribbon so you can also remove them easier, if you utilize the pull ribbon and thread it between the batteries. This device quickly became part of my weekend coffee routine, and I also purchased a lesser model to bring to work. (This 'Executive' one, has a holster stand, which looks nicer, and seemed to cradle the frother, instead of hooking it into the holder.)
I was so happy with the frother, I was sad that one day it seemed to not be working quite as well. I thought .. hmm, maybe the batteries need to be changed? I changed the batteries, and was still experiencing it not really working. (I would press the button, but it didn't start frothing right away, and then seemed less powerful in a way when it did start. But, it did still froth.) After a second day of experiencing the same thing, I reached out to Zulay. They are gracious enough to have ALL of their contact information printed directly on their box, underneath all of the beautiful information about the company, and where / how it began. It was on a weekend, so I chose to send an email describing what I was experiencing, and asking their advice. Based off most recent attempts at Customer 'Service' with other companies, I didn't really expect to hear back. Not only DID I hear back, but I received an email from a human, not just a system-generated response with canned information. They expressed their concern for my item not working, and assured me they would make it right if given the opportunity. They wanted to confirm my order, to make sure they had the same model in stock. Within hours, they sent me a link to replace my item, and would ship it directly to me, no questions asked. No need to return the inoperable item, no need to do anything but literally click the button and wait for it to arrive.
My replacement arrived, and it was the exact model I purchased. It was brand new, wrapped in package .. not some refurbished item. And, much to my shock and appreciation that almost NO ONE does this anymore, there was a hand written card included in the package thanking me for giving their family run business a shot. Well, I thank YOU for sharing YOUR family with us, and for making me feel a little like a piece of yours!
I would highly recommend this product, and would certainly purchase it, or others, in the future. I would certainly also be comfortable gifting this item.
Enjoy!
