This is a well made product and should be waterproof. I have two problems with this. 1) The packaging does not match the image shown on the Revain website. In one of the pictures showing the back of the box you can see that it has mounting tabs. They don't, or at least they weren't there with the device I received. The kit does not include the ability to install a box. You must do something to fix it. 2) The seal around the lid is very sticky. This can make it very difficult to open. When I first got this, I had to use a screwdriver to pry open the lid. It looks like the rubber hasn't fully cured. I'll try covering it with some oil to see if that helps. Despite the issues mentioned above, this is still a good box for the price.
