Little disappointed  with the advertising of these as window box planter. If they are window boxes the I would have expected that the hardware that is needed to mount them would be included with them. Unfortunately,  that is not the case and it will cost an additional $60.00 per box to purchase that hardware. Suggest that you advertise these a flower box planter or include a statement in the advertisement that mounting hardware is purchased separately. Happy with the box but this is the reason behind the low review score.
