This is so slim and elegant I was surprised by how little space it takes up as opposed to the unit it’s replacing. The batteries came with it, so all we had to do was “plug and play”. Very simple. The thing that I really LOVE about this unit is the display. I’m now at the age, where things are much harder to see than they used to be. This display is brightly lit and the numbers and units are large enough for me to see without my readers! I put a large mixing bowl on top and was still able to see the display with no problems. Moving the bowl did not change the measurement display (my old scale would only give an accurate measurement if the item was dead center on the unit.) It was also very easy to wipe clean and stored perfectly on my shelf by the mixer. All in all I am very happy with this purchase and I’m seriously considering buying another for my wife to use for her soapmaking.
