This box is very strong and the plastic is easy to pierce through for my bulkhead connectors without tearing. The lid closes and seals well and I'm confident it will keep my gear dry. It had a vacuum in it so it was impossible to open the door until I drilled my first hole. Keep this in mind if you don't want to poke holes. I tried wrapping it in an electric blanket for an hour to break the vacuum and prying it open with a large screwdriver. it wouldn't budge. Again, the box is very solid. The only negative I can think of is that the hinge pins are already getting a bit rusty (2 months) but for the price it's above expectations.
