Product review (4 stars): Good but suboptimal size....
Being from California, humidity is not a big issue.  House humidity may shoot up to 60% during rainy season, otherwise around 40%.  I bought it mainly for the storage and the humidity control is just the bonus.  The item came well-packed, no damage or whatsoever.  Given Prime shipping, the quality of packaging/shipping may have improved.

The cabinet is lightweight, which is a plus but the storage space runs a bit smaller than what I thought.  I kept the for foam for the first two drawers.  In the middle drawer, I kept my canon 70-200 mm and 100-400 mm,  there is only room for one more telephoto lens.  As for the top, the foam is in groove.  I lay my lenses flat, but the grooves were thin, doesnt fit 85 mm F1.2 well, even 16-35 mm is a bit thick for it.  I guess one could remove the foam and lay the lenses upright.  So, I manage to fit 16-35 mm, 35 mm, 50 mm, 85 mm and 100 mm macro.  Have room for two more shorter, more skinny lenses.  I stuffed the bottom shelf with two cameras, two flashes.  Overall, I think the size of the suboptimal if you want to build up your collection in long range.
