I've had for about two weeks now, and I find it totally worth of buying! Fits great in both pocket and very great in hand! Works great as you could expect from a DNA chip. However, it is very able to get scratches. I was affraied of the battery, but it holds up great. With regularly use, I can vape on it amost all day. Some times and in some situations the battery "door" will get a little hot, but it's not that noticeable.
If you have not bought it yet, DO IT :-)
Hope you find it usefull, despite my far from good english :-)
