It very simple to operate and setup. Fill with water, wait 3 minutes and turn on. Lights are not preferred and can be turned off. It works for its intended purpose (personal use). I'm on day two and I have seen a drop in performance, but I'm thinking it may because it's a bit hotter today.
It's not perfect and could use some upgrades on performance. As it is, it's not amazing, but there aren't very many alternatives.
Bottom Line: Yes, I would recommend this to a friend
