The service works well particularly for people who have a hard time finding care for ADHD in their areas and/or a hard time filling the script. The price is a bit expensive if you compare it to receiving the same care from a psychologist or a PCP but again worth it for those do not have easy access. The delivery from the mail-order-pharmacy is good and comes Fed-Ex 2 Day. I have never needed to do a return or refund through the site.
