Unfortunately, during my shake down weekend, I discovered a lot of the features either didn't work, didn't matter, or turned out to be downright annoying! Right off the bat, all those features and space for the battery made for a large carry on bag that doesn't really fit my usual amount of stuff inside. It's the biggest carry on in my closet and most likely wouldn't "fly" on most European low cost airlines. It fit what I needed for a weekend, but would not have worked for a week or a trip where I needed extra equipment for activities (snorkels or binoculars)
Then many of the features that would be extremely useful in a bag you plan to check, are useless in a carry on bag. And this can ONLY be a carry on bag because it has a lithium ion battery which is listed as a prohibited checked item on planes. (see FAA regs here) In addition to the weighing feature being wildly inconsistent, requiring multiple tries to figure out which number was "right", this feature is also on the list of "doesn't matter" features for a carry on bag because I have almost never had to have my carry on weighed (only ATN air to Papeete weighed our carry ons) Generally, only checked baggage is weighed. Although the auto locking, location and notification features worked well with the app, for a carry on bag, it's rare you let any carry on bag out of your sight for even a minute, lest security would descend on it within seconds as an abandoned bag, no GPS needed! A location feature would be very helpful for a checked bag; if it's not on the carousel, you could immediately tell the baggage crew exactly where it is, but that brings us back to the fact that you can't check this bag!
Lastly, the annoying features- I didn't like having to turn on my phone, open the app on my phone, then unlock the bag every time I wanted to quickly access something in it (there is an included emergency key you'd need to carry in case your phone dies) I also found the blue steady and blinking battery indicator lights to be very disruptive in a small hotel room. It's hard to sleep with the bag charging and flashing blue LED lights all night, and many hotel rooms might not have a solid door to hide it behind at night.
So now this case is now collecting dust in my closet, and at well over $200, it was an expensive mistake. I guess I might use it if I was taking a trip where I expected lots of "land" (not flying) handling of my baggage, such as tours where the bags are left on the bus and transferred to your room each day by hotel staff, but we don't take too many of these kinds of trips, so it's likely to stay in the closet for a while!
Fortunately, many of the investments I've made in travel gadgets have paid off by being useful and making my travels much easier!
