It really depends what's most significant to you. Most kitchen scales are all to easy to use and reasonably accurate, however, if you want something quite easy that doesn't need batteries, then go for just a mechanical scale. If you wish a precise, an easy task to read measurement, look at a digital scale. Whichever way your going, the measurements should be very easy to read, the controls an easy task to use, and also the continuous weighing function ought to be reliable and act as promised.
You wish to have a large enough platform area to keep most of your ingredients, however it is not a crime if many of it hangs within the side providing it is balanced and centred within the platform and you'll still start to see the readout.The tare function simply resets the dimensions to zero. If the model enables continuous weighing, the tare function permits you to weigh a brand new item without treatment of old one by resetting the scales because you weigh. That can be handy if you need to mix set numbers of ingredients from the one bowl, including flour, sugar, etc.
