I had one exactly like this and it lasted about 4-5 years. I use it a lot so the stand eventually wouldn't stay locked in. I wouldn't use any other kind.
It works but I have to re-clasp ONLY the left side of the back support EVERY TIME I want to use it. The right one stays clipped in perfectly but the left one has to be re-snapped into place each time I use it. Also it would have been nice to have a little lip or edge on the bottom of the paper holder ... that way the papers won't slip out when you have quite a few pages on the stand.
A neck injury from many years ago still flares up when I need to look downward for long periods of time ~ which is the case at a new office job I have so after reviewing many desktop copyholders online I chose this one due to good reviews I read and great low price. What keeps me from giving it a 5 star rating is that the clip that holds the paper doesn't hold them tightly enough (like the old fashion clipboards do!). Aside from that I love this neck-saving copyholder!
