This light is meant to be used with the new M-Edge Kindle covers. Rather than have a clip, there is a small plastic bar/tab that slips into a slot behind the kindle (to be honest, I did not even know it was there until the light arrived - I envisioned it would go in the elastic pen tab). Very slick. It does not interfere with the kindle in any way.
-Lays flat beside kindle, cover easily closes over it
-No big clip to worry about
-Battery easily replaced - screw top design requires no tools, battery size like that similar to garage door opener
-Flexible arm easily conforms to any place you want it to be
-Blue hue reduces glare and is not harsh whatsoever but plenty of light to see (woohoo!)
-Arrived with battery
-It seems a little short at first which results in uneven illumination, but length is of course limited (I've adapted)
-Seems to attract dirt in its seams (mine had some coming out of package)
-Obviously, because it is made to work with the kindle, it doesn't have a clip or stand to work as a stand-alone light, which other options have
Since my big grievance has been toting around my large Mighty Bright light, I couldn't be happier. This light has zero footprint, easily fitting inside the kindle cover when closed.
While this does not pertain to the light, unlike other reviewers, I have nothing but positive things to say about M-Edge customer service. I was contacted by two customer service reps via e-mail 1) regarding a cover I returned and 2) regarding the light's shipment date. They were both extremely pleasant and gave accurate information. My light arrived 12/26 and was ordered the end of November.
