I like how it is easy for us as office staff members, when we are taking care of patient appointments or procedures; all that has been done before me! It's not hard at any time once one learns some tricks in order so get used too quickly!! Just be sure about everything because sometimes there can go wrong just by little mistake which would make things worst than if they were right way first place. So try learning more then using only 1st step method since i think most people don't have enough skill but also know much better ways after few days/weeks usage. !
