With any software the key point of determining the overall usefulness is the ratio between the price and variety of functions you have. Well, Zoho has never let me down yet and this is another great example of them providing immense quality to your networks - health monitoring, mapping, traffic analysis - there are more than enough ways to improve the way your network functions.

Instead of actually pointing out flaws (as there isn't really anything to discuss), I'd emphasize more of the great sides. One thing that stands out as I already mentioned the quality aspect is the price - it is one of the cheapest solutions available considering the extent of function you get and there is even a free trial.

Zoho solutions are always top-notch and shine with simplicity and functionality. The same applies to this one as its' immense feature set is supported by amazing interface - all of that with a very reasonable price tag. It's also supported internationally which means you are not very likely to be left in trouble with your questions or worries.
