The product has been very stable, reliable & easy enought use that even non technical people can implement it without any problem at all! I am working with this software since almost 3 years now (since version 10) so far there was no issue whatsever! It's really great :). Nothing specific as you might think about other products out ther but just try first before buying anything else because they are not cheap like some others vendors would say or claim :) We have solved our need regarding high availability by using HAProxy VMs running inside virtual machines within one physical server which also runs Oracle Database Server 11gR2 RAC environment - we needed something similar having two different OSes/platforms where both should be available 24hrs per day / 7 days week etc..
