Before I knew the producers did not, but wanted to try it anyway times - and I was not disappointed.
The case is perfectly manufactured. Rolled himself completely fully charged cleanly and with little effort - it must be.
The layout inside is reasonable and well thought out. All zippers go on cleanliness and. The case itself is very lightweight and portable - perfect as hand luggage (but does not accept any airline this case size, Lufthansa and Air Berlin I had no problems).
I was a total of 3 flights with suitcases (foreign and domestic) - you see it on the trunk barely, everything works and he has barely scuffs. I'm very satisfied and therefore the trunk and the manufacturers recommend.
