product arrived and seems to work as stated

I feel the plug that I received with my original demer box was defective and should have been replaced at no charge

Does the job

Lost my old port plug while taking a raft down the fish ladder of the Rogue River. When I jumped across the raft my foot snagged the protruding twist part of the plug and it fell into the river. I recommend buying a second one to keep on hand. I finished the trip with my demer box in a dry bag so no water damage. It’d be cool to have a version of the plug with a flat top profile. Maybe one that twists from the inside of the box… 🤷‍♂️ Im no engineer though. Just a raft guide ;)

was sad to have to purchase this after the first one broke, but it's a great product and excited to have my water proof functions back!
