Title: Good Idea - Bad Execution
Review: I have owned one of these for several years and it has been falling apart almost from the start. If you look closely at the picture you will see that the box portion is made up of two plastic halves snapped together. If you put more than a few sheets of sandpaper in each tray, the middle of the box spreads apart along the seams from the weight which allows the trays to come out of their grooves and fall on top of each other. I plan on making a plywood box with grooves for the trays and throwing away the plastic box, but the box should have been made of a lot heavier material and not contain a seam.
Is the review positive or negative?
