it just did not fit on my WFH desk and you could not put more than a few pages on it before it collapsed. the "ruler" like feature (sliding) did not work. I returned it.
It worked really well. I am a bookkeeper and the ruler adjust up and down thru the document making it easier for me to see where in the page I am. I personally like that feature. It doesn't fall over wither like other I had in the past.
This is a very handy paper holder for making it easy to copy when typing a document. The only fault I found is that the clip for holding the sheets is a bit loose and it is necessary to insert over 5 sheets for it to stay in place.
