I have been using the Pelican 1170 for several years. I don't care about waterproofing or pressure relief, I just need a functional case to carry my gear. I ended up needing a second case, but the $50 price tag for the Pelican 1170 is pretty painful. I decided to buy this MIEJIA case. The sizes are identical. The processing quality of the exterior and interior is almost the same. Can't speak to waterproofing/pressure regulation, but I suspect the Pelican wins there. The MIEJIA pressure valve is actually a small screw that you can screw in and out to presumably release pressure.
