Very easy to assemble with no tool needed, except for installing the air-shocks for the lid. It is very roomy, larger than I was expecting. 4 stars because it is a little bit flimsy until the lid is close, and the front panel and the lid doesn't meet perfectly so the hole on the lid and the hole on the front panel aren't lining up perfectly in order to put a lock through them (I don't really care about it but someone may).  I am thinking of buying another.
