i have been running this product all through the beta. (about 2 months now) it has come along way....
my company will be buying it first QTR 2011. (had to wait for the bean counters to put it in the budget)
while it is not as "complete" as Diagnostic Manager or SQL Ignite, for the price, it is great!
RedGate has a forum for users and testers to make recommendations and voice complaints. they are very quick to respond and tell you if they can help or not. for example, I said they were missing an alert for failed logins and they responded back with in 6 hours saying it will be added in a future update.
thanks RedGate for another choice for SQL monitoring.
