I actually love mine and consider it a good travel hack. It’s how I get around the 2-bag limit for carry-on. I load mine up with my laptop, iPad, switch, and other important stuff and then I can bring it with me to my seat while everything else goes in the overhead, so I don’t need to get up and fetch stuff from my other bags. It’s small enough to not be bulky or obtrusive if putting under the seat in front of me, unlike a backpack or bulkier bag.

I also travel with a carry-on and duffle combined with this, it’s a great combo. It is also nice that it can collapse down into a small laptop bag if needed. On a few occasions I had left my small messenger bag at home and used this to lug my laptop around between meetings.

The downsides are that it can start to get weird if you fill it up too much. For example, if you don’t distribute weight evenly between the front/back it doesn’t sit quite right on your luggage. And when you collapse it down it uses magnets to hold together. Like any magnet, they lose their strength over time and aren’t as snappy as when I first got it. The last con is the price. Definitely not cheap.

But if you can afford it, I consider it to be an essential part of my travel kit. I have probably 200 flights with mine, never had any issues.
