Bag / Booster bought for a plane trip + car there, the concept is really great. This was to prevent us checked baggage. The problem = capacity: Full size business with 4 years for a day ... even just three days clothes do not fit (tested with different techniques of folding, nothing to do interior is tiny, the banks take in. 4 cm all around .. To the beach one day, perhaps ... and without inflatable crocodile) but considering the price (with 3 children) product returned the same day, because really unusable. 2 stars for a great concept, but can be improved to increase capacity (By cons as always quick and easy return and refund, sav amazon on top! :))
