"I have three spice stacks and love them, just wish they were a little higher quality (plastic is sort of cheap looking and flimsy).  The idea is excellent though, mainly because with labelled drawers you never "search" for spices.  You just organize them alphabetically, label the drawers and grab for a spice without hesitation.  Many solutions are just trying to make the spice storage more dense, but don't actually make them much faster to find."
