So far so good!
I haven't yet used the carry on on a trip but I was happy to receive it. The dims are exactly what I needed to fly with European companies (French Bee especially), their requirements are different and until Antler, all the ones are checked were too big.
This is not to mention that the suitcase looks really nice, rolls smoothly and seems to be good quality! I look forward to taking it on a trip, and will most likely buy a second one.
