I like that it is free to use, easy for users without IT experience or knowledge of Linux command line tools can easily deploy in their environment with minimal risk/cost (which are usually big obstacles when working outside your org). It has some good features but also many quirks from time-to -time which makes troubleshooting issues more difficult than necessary sometimes; especially if you're not an expert at linux commands yet! Also there's no way around having multiple tabs open while using HA as each tab will have its own separate configuration information about VMs running within one host server / ESXi Host Server instance so make sure what type(s) do need monitoring before installing this software!! If any other product exists out here then be aware they'll likely offer better support compared even though we've had great success solving problems together via email communication over Slack channels etc.; however nothing beats face 2face interactions either between customer service reps & customers themselves OR direct access into our servers by.
