Shipping was fast and came in good shape. However, this scale weight seems awfully expensive...

As always the best service and the best prices on the net! The only place I buy my scale needs. I always recommend "OldWillKnottScales" simply cause they have what you need for great prices and as mentioned their service is second to none. Thank you
