I am 74 yrs and it was so difficult for me to "click" the sides to the bottom.  It is not insect or water tight and there is not enough room to put your hands into the side hand holders.  If it were not, after 2 hours of struggle, together, I would want my money back.  I also need a bigger lock as everyone I have does not work in the opening. 1 star only because it is quite large.
