First the criticism: I bought this because of the reviews saying that the battery life was long, however the battery only lasted a week for me, on a full charge... also the way the color temps cycle through is not smooth: it goes cool, then warm, then in-between.  The magnification is scary big, and you have to be super close to the miror for it to work!  I'd prefer 5x to 7x...  But the positives outweigh the negatives so far- I like the shape of the mirror, and it is easy to move around, I like the touch button to turn it on and off, and I'm getting used to the HUGE magnification- it lets me see details I didn't know existed, which is a good thing!  Hopefully it will hold the charge longer as time goes by?  I don't want to have to return it.
