Review on WebWatchBot by Seth Singh

I like that this allows me access from anywhere in any device (even my phone).

The notifications when something changes is great! Notifications can be set so you do not have an email blast everyday, but only if there's been some change or error detected within your website/domain etcetera.. It works well with WP Super Cache plugin as it will notify of cache errors which helps keep things working properly without too much hassle after updates / patches come out - sometimes they go wrong though!! This does help alot by allowing us alerts about such issues sooner rather than later before we find ourselves having problems due our websites being down because caching was off somehow :D.
