I know it's been several months since I was debating booklights, but just wanted to throw in my $0.02 after using the eLuminator Touch for a few months
1. I
really like the touch portion. I was a little worried at first that it would accidentally get turned on in my bag and drain the batteries, but no worries. The touch is only activated when touching it with bare skin (i tested this out with very thin gloves - the ones I used in marching band). The absence of a switch is, to me, a plus. The more streamlined, the better.
2. I've since switched from my original mCover to the m-edge Latitude Jacket. The light worked very well with the mCover (I could just slip it between the kindle and the cover, but having a dedicated pocket on the m-edge cover is very handy.
3. Some people have complained about the fact that this light shuts off after an hour. This is slightly misleading - it shuts off after an hour of
inactivity. I read a lot in bed, and have been known to fall asleep reading. I love that it turns off after an hour so I don't have to worry about draining the battery while I sleep. I do tend to read for hours at a time, but this isn't a big deal. When the hour is up, the light will flash on/off several times. All you need to do is touch the touch area once and the light will stay on for another hour. The hour is also reset each time you change the brightness. So say you read for 30 min at brightness setting #1. You realize it's getting darker and bump it up to brightness setting #2. It will shut off one hour after switching to setting #2.
3. One thing that I think could be better is the gooseneck flexibility. Yeah it's great that it stays in place, but mine seems to be a little too stiff to stay in the position I need it. Now that I'm using the m-edge cover with the light, the light is now directly behind the kindle, instead of off to the side, like with the m-cover. My reading angle is just weird enough that the bottom of the page doesn't get as much illumination as I'd like now that I have the m-edge cover as well. The gooseneck DOES stay in the positions that it "likes" and seems pretty sturdy.
All in all, I'm pretty pleased with the e-Luminator Touch. The paperclip back makes it easy to use on paperbacks as well - an added bonus
Hope my thoughts are helpful to anyone out there still questing for that perfect light!
