My son loves this. I wish the battery came with it, but we knew that when we purchased it. Everywhere we go people ask him about it.

I really the display that you have an option to choose and make the change it. You could also created your own text to display or download the one it has already created by the manufacture.

The lights help you be seen at night, which is useful for safety. Its big enough to fit a helmet in it, when its empty its light, and its comfortable to use. i like mine it looks super cool at night

This motorcycle backpack is not bad. It is protective and durable. The eyes are two different screens places on the backpack. It is a solid hard shell to protect your back if you happen to fall. I will say that it mostly will damage that screen. You do get the option of changing the eyes though through the app which I feel could use a little work. It sometimes has a hard time connecting and the UI is not the easiest to follow. The screen have worked out pretty well for me although do not expect a ton of realism. The backpack solid shell makes it difficult to have flexibility. This is also due to have a screen so do not overfill bag or you may damage it. The next thing is that you do need a battery for power in order to keep the screen working. This means you need to carry a battery pack inside. In terms of space, this does have a good amount of space. The zipper is also solid so you do not have to worry about it breaking. There are a bunch of things you can show on the screen in the back. The picture quality is okay but again do not expect realism. I do love that the eyes give it more of a "creepy stare at you vibe" Overall this motorcycle backpack gives a whole new meaning to "watch your back" when riding around in this thing. I love that you can customize the eyes to reflect your personality. You do need to pair your phone to this device in order to do that though and download the app. You also need to be aware that you need to carry a battery pack as well to power the screen. The screen is small so remember that. It is just for the eyes. Some eyes really work for this while others do not. The straps are also solid so you do not have to worry about the strap breaking.

this is really cool backpack this was easy to set up. this is well made pack, these are light wt . this would make a great gift, I would recommend to everyone. love it
