I love Hatch. I've now owned both generations of the sunrise alarm - the first generation (bought in late 2020), and now the second generation (bought recently in late 2023).
Across both generations, the clock is great for both going to sleep and waking up - I like setting the nighttime routines of a nightlight (for reading, etc.) and then fading into white noise to go to sleep. The system helps you actually set and stick to a nighttime routine, which doesn't really happen for me unless I have the light/sound cues. (If I'm away from home and don't use the Hatch, I don't stick to a routine.) And then for waking up, the sunrise system is definitely much gentler than a harsh alarm sound out of nowhere - it's pretty lifechanging, honestly, particularly for an extremely-dark-in-the-winter place like Seattle when you wake up early.
I will say that the first generation alarm was quite buggy - the app wouldn't properly pair with the clock, the clock would disconnect from wifi without explanation, the light/sound would act up at bedtime (the morning alarm always worked, thankfully, for some reason it was just the nighttime routine) - so that was a bit frustrating. I would have given the product 4 stars at that point. I was slightly nervous to buy the second generation device because I knew I'd be really frustrated if it had similar issues, but so far I've had zero issues in the few months I've had it - so now I'm up to 5 stars.
