These are the most accurate set of scales I've ever owned. They were easy to assemble (just attach the base to the top w/ 4 bolts and then screw on the wheels w/ 2 more), simple to zero (twist a screw until the balance hovers in the middle), and accurate (they match to within 1/4 lb. of the scales at my weight loss group). These aren't light, flimsy scales, either, so I'm glad I got the wheel kit. I'm not disappointed.Get more detail about HealthOMeter 402LB (Health O Meter) Physician Balance Beam Scale.
