Review on 💪 Exceptional Strength and Durability: TITGGI - The Ultimate Concrete Professional Industrial Solution by George Johnson

DO NOT BUY FOR CONCRETE. I had to drill some holes in a concrete wall. I was able to make 2-3 holes before the head flattened out. It worked, but I wouldn't recommend it for concrete. Definitely something softer like wood or glass. It served its purpose so I'm happy with it. I think you get what you pay for. Otherwise this is a good piece.
