Review on Hestya Calibration Digital Balance Tweezer by Jeff Kersey

I was expecting them to come in at least a box but they didn't, they came in a resealable plastic bag. One of the scales I bought had a 50g weight and two cut outs for two weights, so I put two of those weights in and left the other three in the resealable bag that came with it. The tongs are good, hold the weight well. I tested the weights on two scales, one to three decimal places and the other to two decimal places. Both scales showed the same weight values. Some weights were off by about 0.001g on a three decimal scale and 0.01g on a two decimal scale. Not sure if they are weights or scales but since they read accurately for other weights I can only assume the other weights are disabled.
