He misses its best feature, which is that it's the largest capacity spinner (four wheel) bag available in the USA that meets the domestic airline linear inches limit, and has a wheel lock (brake system).
I don't know why that isn't a more popular feature.
It's such a pain when you've got that start rolling away.
Roller board (two wheel) bags stay put, but are more difficult to handle when you've got a lot of luggage, which is just when rolling away is more of a problem.
So the Delsey is sort of the best of both worlds in that respect.
But the rest of his review makes up for that oversight.
