Bought so it'll fit my 15 inch notebook but it does not fit. After a few manoeuvres, all it fits is my iPad Pro and few few packets of tissues. I had to keep the computer charger in the main compartment as well. It's very slim so you'll have to manage your item's carefully & the added security lock is a nice feature like most other cabin luggages. Main compartment and wheels are as described. I have not tried using the usb or cup holder but I'm sure it'll work and nice to have though I honestly don't think it's necessary. I initially picked a yellow colour luggage but they said it's not available. They were also very polite/apologetic and delivery was within 24 hours when I told them that I was flying out soon. Since the bag is made of aluminium frame, I find the edges may be quite razor sharp so be careful when closing. I did get this during a sale and overall for the price paid, it's a decent purchase and I see myself using this for future trips.
