I've had my Hatch 2 for 18 months now and I love and hate a lot of things about it. Overall, its a great alarm clock and white noise machine. The white/green/brown noise options are especially helpful if you live in an apartment and need to block out neighbors while you sleep. The sunrise wakeup function is similarly great and wakes me up most of the time before the alarm sound does.
The biggest cons I have are the subscription, the app, and the consistency of the machine. Most of the apps best functions are hidden behind a subscription fee and can only be used if you have the app. You can't program the clock without the app and it isn't very intuitive. I've also had issues across multiple hatches with the sound suddenly stopping in the middle of my night routine.
This also may sound silly, but if you are like me and use a sleeping mask, skip this alarm as it loses its main function!
