I really liked this little light box. Solid product First, super bright when you want it. This clip is very useful. Allows you to attach it to many things and even place it on a surface at an upward angle. The battery seems to last a long time. It uses a micro USB, which I often keep nearby. I like to use it for videos and photos. It's great if you just want to take some selfies. I personally use it for live streaming on my phone. It attaches directly to my phone with a clip and is lightly rubberized so you don't have to worry about scratches. The only problem I have is that it crashes sometimes. It behaves like it's out of battery, but as soon as I turn it on, it blinks rapidly and seems to "reset". Then it works again without problems. Happens every now and then. It's not really a big deal unless you have the option to top it up at an ATM, which can be a disadvantage if you really need it for something (camping, finding something, train). In general, I dig it.
