Query: Not for Kindle, and not great Q/C

I purchased the Multi Flex to go with my new Kindle eBook. Amazon recommends a different model, the Ultraflex2 by Mighty Bright, but they were out of that and this was on sale. They look almost identical in the pictures, so I figured it would work.First problem- did not work out of the box. I tried multiple battery sets, it would not turn on. At least in my case, the quality control is lacking.Second problem- it will not clip on to the Kindle. Only the bottom of the clip has anti-skid rubber stuff. The top clip is just plastic with not much contact area. It probably is fine for clipping to a normal book, but it would not provide a stable hold on the plastic Kindle. I do not know if the Ultraflex works better, but will find out.My rating is based on the Multi-flex not meeting my specific needs, and not working at all out of the box. If you get one that works (it appears most folks do) and you are going to clip it to a normal book, it might be a fine choice.
