Easy to build with two people.  Very light and easy to move.  Had two people sit on it that weighed over 400 lbs together to test the bench.  Lots of storage space inside.  Says it is weather tight but I plan to put a locking plastic bin inside to be sure.  We did not leave the metal locking pieces on because our clumsy dog may run into it since this is in her play area.  The piece sticks out a little.  It was easy to install.  This does not feel as tough as other outside storage bins we have had.  Time will tell.
