I initially ordered this light because I wanted something small and flexible that I could leave next to my bed and use to read at night and it's works like a dream for that. But now that I've been using it for a while I've learned it's actually good for so many applications! It's has three levels of brightness that are easy to change with just a light touch to the power button in the center of light. One of my favorite things about this light is that when it's folded it you can still see a circle of light so it works perfectly as a dim night light for just walking down a dark hallway without stumbling but it's not so bright folded that it will wake up the whole house. When unfolded the different brightness levels are great, I use the dimmest one for reading in bed in a very dark room and the brightest one for doing paperwork at night in my office. It's also so portable it's great to just grab and carry it into the closet if I need a little extra light in there. After being fully charged with the included USB cord (it doesn't come with the plug so it can just be used with an existing phone charger or computer USB port) the charge lasts for at least 3 hours before it runs out. I haven't actually tried to run it longer than that without charging it again so I can't say exactly how long it will last before it dies, but I imagine it could go even longer than I've tried to use it.
The only cons I could mention about this product are that a) it doesn't lock closed when it's shut so it does slide open when it's folded - I think it would be more convenient if it had a little latch or magnetic closure so that you could use the folded wire neck as a handle. And b) I wish they had used a mini or micro USB port as the charging port on the lamp so that it would be more universal with other products and I wouldn't have to carry around this charger cord in addition to other cords when I want to take it with me travelling. That's not too big of a deal though so I'm not taking a star off for it.
All in all I'm really excited about this light and so glad I purchased it. It's absolutely worth the money.
