I like that it's very easy to set up with all of your different types or servers (web server(s), mail system etc.) And also how simple you can add new type if needed in future without much hassle at least from my experience so far! It doesn't seem as user-friendly compared other tools out there but maybe this was due its young age? We are using sawmills only because we have not found anything better yet since they were just released last year by our hosting provider who had nothing good either -.- So no complaints about them really except their price which isn´t cheap anymore nowdays anyway ;) Maybe try some free trial first before buying something important :) Like others said above; logging errors would be nice addition too when possible instead having separate app running alongside each one separately :D.
