I bought this holder because I read on my Kindle every day during my coffee breaks. The constant presence of the Kindle in my lap gave me neck spasms. This holder keeps my Kindle Paperwhite perfectly in its case. I'm hanging it on my shift to keep it safe. It has some cushioning in the clamp so it doesn't scratch the shifter mechanism. This allows me to read at a comfortable distance while looking at the device in a position that doesn't strain my neck. The only downside I've found is that the rigidity required (to hold it in place) makes it a bit difficult to locate the holder's gooseneck in the correct position. But once you get it right, it definitely won't move, so you're done!
