The DiveBag is with me (like many) for use only as a travel trolly in. However, it meets all the requirements for a great price / performance ratio. We had him packed for our trip to Paris in use and was "full blast". However, no trace of buckled wheels or the like. This problem I found many times in other trolleys or travel bags with wheels fixed and was always the reason why they were retired. However, this one shines through plus easy to clean durability. The backpack function works very well, even though a chest strap had greatly increased the wearing comfort. However, he makes such a good figure.
