Congrats Riipplinger! I'm really liking mine. I don't find it to be yellow though but that could just be my eyes. I played today with using the B clip and something to make it snug and it works better than just pushing it on. I wanted to use that one so that it sits on the reader's edge fully.
I added a piece of rubber shelf liner to the inside of the clip and it seems to be perfect so far. I didn't glue it or anything I just cut it so that it fits and have it so that it sits under the clip front to back. It doesn't show at all and it seems to fit perfectly with no wiggling at all. It's the non-adhesive kind with the little nubs so you can cut it to fit your shelf or whatever perfectly. It comes in several colors too so you can make your decor or in this case your reader or light.
Regarding the tight USB connection, try opening the arc light, plug in the USB and reclose it rather than plugging it in when the light is in the off/closed position. I noticed it tight too but then did it that way and it went in and out better.
I used my Blackberry charger to charge the reader and the Arc light and it works great. I got the green light indicator overnight charging it that way.
I'm loving it so far. I had to laugh because the hubby commented on which number of light this one makes for my 'collection' the other night while reading in bed. LOL I showed him the difference between the Arc and the clip and even he said 'oh wow'. LOL I got quite a chuckle out of that.
