The cupholder doesn't really stay in place, it won't lock in the right position, so I'm not sure how useful that feature will be. We still need to test the USB charger feature - I thought the suitcase came with it's own power bank so that's a little disappointing too. However, it was a great deal and as a basic suitcase I'm sure it will work great.
Wonderful piece of luggage! Love the features: cup holder, battery charger & phone holder. Others who saw me with it, admired the features and appreciated the hard cover as I do. Then proceeded to purchase a set for themselves!
