The best part is that it's very easy to set up with no technical expertise required! It even has its own dashboard where you can see how many people are using voodoobrowser/vodooalert from which devices they're accessing our site etc., so we don't have any problems monitoring this service as well because of all these things I just mentioned above (and more).
Sometimes when there was an issue or error while viewing my sites' performance online through their tool sometimes i would receive emails stating something like "your page isn’t loading". This really annoyed me since every time one such thing happens then everyone who sees those errors will think negatively about us - not good at ALL!! If someone were thinking otherwise before seeing them than definitely after reading some negative reviews he might change his mind but if nothing else what could be done? They need improvements here & should do better research.
