Review on 💎 Kingthai Diamond Concrete Connector for Masonry Projects by Bim Cook

Punch two holes in 3" of unreinforced concrete with water cooling and lube, then lose one of the "prongs". I don't think it would be useful on any other hole. Expensive two holes! I will be buying USA made in the future, may be more expensive in the short term but will prioritize durability over cost.
