It's easy to use with very clear instructions for both novice users as well experienced ones! The support team are always willing & able help you out any time of day or night should your problem arise during working hours (GMT). I have not found anything that could be improved upon in this software so far - it does exactly what we need from an operational point-of view without being too complex / difficult/ expensive etc.. We're using fireflowl mainly inside our office but also some locations outside where there isn't access via VPN due to security reasons.
