Rugged device. Much more useful than the flimsy fish scale that I had before, and cost only $10 more. I tested it at various weights and found it to very reliable, well over 99%. I don't have a way to measure accuracy. Display is easy to read from different angles. Hardware (hook and hanging shackle) are very robust, but a bit cumbersome and probably oversized for its 600 lb capacity. The built-in tape measurer is superfluous and I doubt that I'll find much use for it. I would purchase again and would recommend to others.
