Review on CEEYSEE Connector Insulated Connectors Set（RSZ by Jose Schweigert

I'm making some upgrades to my boat and need a cable lug that is REALLY WATERPROOF. Many of Revain's "waterproof" lugs are not truly waterproof, only resistant to splashes etc. Once installed on the cable you can heat shrink them with a lighter or heat gun. Very reliable connections with a decent crimping tool and waterproof too.
