### ⭐⭐⭐⭐⭐ The graphics are cool!
*by T***P on December 30, 2025*

It was a Christmas gift for my hubby. He LOVES this bag. His only complaint involved the app. Outside of this, is perfect!

### ⭐⭐⭐⭐⭐ LED Life great
*by S***K on June 14, 2025*

My son loves his new LED Back just have to figure out how to operate it

### ⭐⭐⭐⭐⭐ Nice Pack . . . with Really Fun Lights!
*by F***N on April 5, 2023*

This LED backpack is made of high quality materials with precision manufacturing technique. The pack is assembled cleanly and all the seams are straight and tight, and the zippers work smoothly. There is ample space inside, and the LED light panel on the back portion doesn't really take up any space on the inside of the pack, as the light panel is somewhat flexible is is quite thin. There is a batter connection on the inside, with a USB-A cable for you to plug into a power brick or battery. There are also convenient pockets to store the battery and an extra. Pairing with a phone is easy enough, though you must use the manufacturers app. It doesn't ask for too many permissions, so I trust that the app isn't taking over my phone. It asked me for photo gallery access , internet, and Bluetooth. Could it be sending my photos to China? While possible, I didn't notice the phone heating up, as it would do if someone was trying to download much data from my device, and I didn't notice my network usage go up either. That doesn't mean I won't keep my eye on it, and you should too! That's how you can tell if some app goes rogue on you . . . it starts using your phone and internet connection, which makes your phone hot, for seemingly no reason, and your bandwidth usage goes through the roof. This app didn't do any of that. What it did do, was let you pick from a variety of preset images, or upload your own and tweak it. I'm going to use this backpack to draw attention to a trade show booth, by putting it on a staff member, who will walk around the show, displaying our logo and booth number. I can think of dozens of uses for this nice little pack, and I'm sure you can too! Price is a little high, but you're getting high quality and those LED lights should last a really long time. Nothing bad to say about this Five Star LED Smart Backpack.
