    Haven't used it yet, but first impression is it is a simple design, well built. Have used it to check strength of magnets on piece of oil field pie which will be used for a pipe fence. Holds on to 2 7/8" and larger pipe (vertical and horizontal/post and rail. The free stinger to use with the grasshopper stinger support brackets was a bonus. Customer support great, greatly appreciated on the fly change to shipping method.

    This is a good design and it sticks good to coated pipe. I like it alot better than the javelin brand.
