So I use my drone all the time at the beach, recently upgraded my drone and wanted a new case. I'm always looking for something waterproof because you never know when the tide of blush will come. So far this case has been amazing for sand and water protection. I used it on the beach a few times and after I was done I hosed it down under the beach shower and no water or sand got in at all! It's definitely waterproof! It's really solid and well built, the plastic isn't cheap, it's flimsy. It's built nice and solid. The latch feels good and the pressure valve seems to work well. I haven't taken it on the plane yet. The pre-cut foam is very convenient, I prefer it to the grab and pull systems that some other cases have. Pretty sure I could cut out a few more spots to fit other stuff if I wanted to, but it's not necessary just yet. All in all a solid case!
