Query: GOOD IF YOU DON'T HAVE TO MOVE IT

Somewhat lighter than I expected, but once together, I believe it will be waterproof, which is why I bought it. Make sure to read the instructions carefully because the pieces need to be put together in a certain order, and if you put them together in the wrong order, getting them separated without tearing the plastic is very difficult.
