Don’t get me wrong, it worked for what I needed it for but barely. My counter weight in our water storage tank had come lose and fell to bottom, it was only ten feet down and was galvanized steel. The magnet barely held as I pulled it up. So I tested it, I’m a disabled 62 year old man of whom was able to pull it straight off the side of the tank, I’m talking direct pull with magnet flat against wall.
