Disagree! Except yes, the boxes are a bit flimsy and after a mere six years of beekeeping I have to do some basic repairs this winter ... which is one of the reasons why I wanted to take some of the supers off pre-feeding! - I adjust the size of the 'front' door according to the weather and never have a problem with humidity or cold - the lifts help to adjust the outside temperature gradually. The lifts get propolised but of course can't be completely airtight because of the roof apertures and the front door bit. Each to his own!
