Rubbermaid Commercial Digital Receiving Scale - 150 lb Capacity Heavy-Duty Shipping & Postal Scale with Non-Skid Surface - Perfect for Kitchen, Restaurant & Warehouse Use - Food Weighing & Package Shipping Scale

I just received 3 of these scales for commercial shipping needs. We weigh packages from 1 to 40 lbs. to ship by any number of freight carriers. All three read 11.0 lbs without adjustment with 11 lbs worth of calibrated weights. (Also tested at 1, 5, and 6 lbs on the first scale and it passed all around.) Impressive! We'll see how they hold up, but on day 1 I like them. I do not see a way to calibrate them should the need arise. Also, we do have sturdy, flat tables where the scales will be sitting during use. The digital readout is not huge but will work for our needs.
