Connecticut isn't actually a two party state for the purposes of this device. If you're recording in-person it becomes one-party. In Massachusetts this also wouldn't run afoul of the law because it isn't a secret recording. Michigan is also a one-party for participants which in-person you are. And Nevada is also one party for oral communication.

So you're left with 40/50 states where this device can be freely used and 10/50 states where this device can be freely used because it's a personal device and two-party consent is enforced less than jaywalking for regular people.
