The ease of use - just plug it in! It was easy for us with little IT background at all (but we're still learning) because there are so many options available that you can't possibly try them out without having an expert explain how each one works first hand.- That said I did have some issues when trying new functions but am able get around those fairly easily after doing my research online via YouTube tutorials etc., We've used this software since before our horses were born & never had any problems until now where their food intake has been off slightly due too weather changes affecting feed quality/quantity which leads me think something else might be going wrong elsewhere? But they'll eat well enough if given time even through bad days /snowy winter conditions.
