Let me start by saying, this MTM Survivor Dry Box has become my go-to for keeping essentials safe from moisture. The rugged construction immediately stands out - it's made of thick, high-quality plastic that doesn't feel cheap or flimsy at all.

The triple latch system is rock solid. I've loaded mine with about 20lbs of gear (yes, I actually stood on it at 175lbs!) and it held up perfectly. The O-ring seal does a decent job keeping moisture out - though don't expect it to be fully waterproof if submerged (a few drops got in during my bathtub test).

For ammo storage, it's fantastic. I managed to fit 600 9mm rounds plus 300 .22 rounds by repackaging into plastic bags. The stackable design with four little feet is clever, though they could improve the lengthwise stability.

The compass? Honestly forgettable - it works sometimes but gets stuck. The bright color is great for visibility though, especially compared to the darker green version.

Where this box really shines is as a first aid kit container on my boat. It fits a comprehensive 25-person kit with room to spare for extras like cold packs and flashlights. Just toss in some desiccant packs and your gear stays bone dry for months.

A few quirks: The padlock holes are frustratingly small - you'll need tiny locks. And while the multiple attachment points are handy, the side holes can't actually secure the lid.

Bottom line? For water-resistant (not waterproof) storage of ammo, first aid supplies, or tools where moisture protection matters, this $20 box punches way above its weight class. Just don't expect perfection from the compass or complete submersion protection.
