Very easy for us newbies at our clinic! I like how it has everything we need in one place which makes life so much easier when making prescribing decisions with my clients!! It's not perfect but they are constantly improving this program as time goes by. Nothing specific though just be patient because sometimes things take longer than expected before updates come out or bugs get fixed etc.. We use vpr during consultations/vet visits where i am able find all medications prescribed without having go back through each chart individually looking up drugs from another system (computer).
