Good product - does what it's supposed to
So far, we've been very happy with our Sense. It was very easy to install, and it's providing some additional actionable insight into our power consumption.
We originally selected Sense because of the Power Quality feature they're currently experimenting with. We have occasional brownouts as well as a power quality issue caused by our inverter-based heat pump. Unfortunately, the feature hasn't helped with these issues, but given its "Sense Labs" experimental status, I can't really fault them for that.
