It's very easy to use; it works great in our environment, with only minor hiccups here or there (we're using an older version of SNMP). The UI could be improved by offering more granular access controls so you don't have everyone able see everything all at once! I'm hoping that they improve this soon as we've been waiting quite some time now since its release last year - but overall i would say thats not something too big/bad about snow mirror monitor itself though- just making sure your aware what features are supported before purchasing!! If someone has never used snmp then definitely give them one quick demo run through first because their can get confused easily if given incorrect information which may take several tries until correct info gets entered etc.- otherwise no issues really other than being careful how much detail u enter into each field when configuring agents.
