Quality product.

Fast shipping and exactly what I needed when I needed it

I use this to detect building components that are out-of-level. Cool.

It's big. It's heavy. It's not too expensive. It rolls freely through a 2" PVC pipe. I'll leave the rest to your imaginations. Being plain steel (albeit smooth and shiny) this ball is subject to corrosion. For my application (a free counterweight) I intend to give it a light coating of grease and seal it in with a pack of silica gel to sequester moisture.

superb quality
