LED Backpack, Small Laptop Backpack with Programmable Screen Small Smart Dynamic Fashion Shoulder Bag for Girls and Women Daily Use Cycling Travel Daypack App Control, 12 inch (black)

The media could not be loaded. I am excited to take this to an upcoming tradeshow and have my company logo and some fun messages programmed to display on it! It has a really smooth black finish and the shoulder straps and zippered compartment on the back are nicely padded for added comfort. The sewing quality is good and it has quality zippers. The zipper for the outside of the main compartment appears to be a water-resistant zipper.Inside the material is a nylon with a plastic feel that feels less high quality than the outside, but it seems like it will be durable enough and easy to wipe down. There is a compartment near the USB cord on the inside front that is designed to store the power bank you use to power the screen. Yes, you need a power bank to run the screen. There is no energy storage or rechargeable battery built in. With that said, I charged up a cheap power bank that I received as a promo item at a conference and I left the backpack screen running from 11-6p today and the power bank is only about half discharged so this isn't pulling much power. I also checked to make sure it wasn't getting hot inside. Neither the screen nor my power bank got hot while running it for that lengthy amount of time.The app you download to program the screen worked well on my Android phone. No problems connecting to the backpack via bluetooth and the app was very user friendly. I tried a variety of images and video files from my phone to test out what works best. I included several in the video I uploaded with this review so you can see examples of different types of graphics and images. With the size of the pixels, I found logos display well if the lettering isn't too thin and the top of the screen displayed my logo better than the bottom or middle. Images need to be more square than long in order to display well. If you want to show a person's face or image with people in it, you really need a close up image. You don't get to see any facial features with images that are zoomed out or have more than 2 people in them. Regular videos from my phone lost almost all detail and were mostly unusable. When you write text in the app to display on the backpack, that shows up really clearly. There are a number of included animations in the app, but the choices are pretty limited. I didn't see much of anything I would want to use. There is a really cool free writing/drawing feature! This feature shows what you are drawing or writing on the backpack in real time. You could be walking with your phone and drawing or writing in the app and have your designs or words showing up as you're moving.This backpack is on the smaller size. I took measurements and added photos. It is big enough to hold a tablet or Surface, but not a large laptop. I can't wait to take this with me while I am out and about!

It works but it’s so small it’s unusable for a tall person
