I use the bot in a very limited capacity - I have tried other profiles, but have mainly used it for the regular Nephalem Rifts.
While the bot has its kinks, it works pretty well for Nephalem Rifts and have used it to farm up greater rift keys. It follows its parameters set in the Trinity plugin, such as what to loot, what to attack, etc. The other DB profiles, such as bounties do not work. The developers are aware of most of the major bugs, including the ones I mentioned, so I'm sure they're hard at work fixing them. Personally, I'm satisfied with my purchase (again, I play D3 very casually), but I am looking forward to fixes on the current bugs.
