This bag has been quite the attention getter! Using it to advertise my products without having to say a word is fabulous! I become a living, breathing, walking billboard everywhere I go without the added expense. Clear and easy to read. Love that you can download gifs!I only wish that the two smaller pockets inside were deeper and wider. One of my battery packs is long and slim, the other short and wide, so neither can be secured inside either pocket by the velcro.It's a good bag, sturdy, doesn't feel cheap and I'd definitely order again!Amazing product I bought this almost a year ago and have worn it nearly every day its spacious inside and very easy to adjust the outside display. However It does NOT come with a power source you should buy it with a portable USB Charger. Also as one may expect. It doesn't handle rough travel well (tossing dropping or throwing the bag) the wires may short out.I bought this backpack for a family vacation. Opened the boxed tried it and fell in love. Boxed back and go on vacation a month later the first day it worked just fine. Stop working all of a sudden fully charged battery pack and never worked again. Now the window to return is closed.This is an awesome product and do way to set up. Works exactly as described, received item quicker than expected as well. This was a Christmas gift for my 17 yr old aspiring artist child and a week later my kid is still telling how cool this thing is. Very happy with the product so far.All good , but ... usb power bank should be at list 10 000 maH, so screen is very hungry for power.
