I have professional analog scale and sometimes it is hard to read to where the pointer is at e.g. is it 152 or 153 so decided to get digital scale. Picked this one based on review and the price was good. Got it in two days which was fast. Not sure if it is really accurate maybe I don't like what I see lol. I compare with the analog scale to make sure and they both seem to be on the same wavelength.
