Review on ATPWONZ Waterproof Electrical Underground Connectors by Dave Tapia

Very nice waterproof boxes. The binding posts accept 12 gauge wire, however the wire is too stiff to use. I twisted and soldered every joint in my 100 foot driveway. I also added some waterproof silicone sealant where the wire goes in the box just in case the flat wire doesn't fit perfectly. Cables are held firmly in the box. I am satisfied that they will be maintenance-free for several years.
