Bought this to replace an older iBal201 that was malfunctioning due to old age. The old one kept going back to its programming functions and beeping make weighing a chore to do. I found this scale at a pretty decent price at this internet storefront. My company uses this to weigh plastics samples such as bags or material. The scale functions similarly to its previous incarnations of the iBal201 series. New features on this one include a bubble level for accuracy, and adjustable screw legs to correct the bubble's level. The display is also light up digital which is a plus. The weighing platform could be bigger as its 33% smaller then the older model we own. Suffers from the same problem where putting down a sample would sometimes cause the machine's measurement of weight to continuously keep reducing in weight. Overall satisfactory unit, programming and recalibration takes only minutes with the manual available. When the package came, the box contained the Scale unit, a 200 gram calibration weight, a metallic weighing plate, an AC adapter for the scale unit, and the plastic windshield cover.
