I like that it's so easy to set up (no need of any technical knowledge), also you can easily configure notifications from your dashboard! The best thing about this tool are its alerts which notify me whenever there will be an issue with my site or application even when i'm not online at all time - very reliable service!! Sometimes we get stuck because our server goes down but still gets notified via email / SMS & WhatsApp as well!! So far everything has been great! Nothing really dislike anything yet :).
It would definitely help us save precious resources while working remotely :).
