Nice product. I have raised everything on my desk to help out my neck. This helps with my neck and also makes it easier to read from the page and type data into my computer without having to look up and down constantly. Biggest problem I see is lack of a rubber stop or lip at the bottom to keep the paper from slipping off. Small inconvenience but I think that would make this device perfect and would be relatively easy to accomplish.
For the most part the "Curved Desktop Copy Holder" was a good purchase. The only negative comment I have is the bottom lip is slick and will not hold a document or manila folder unless clipped at top or held on with slider-arm. This drawback is minor compared to other holders I have purchased and thrown away.
