I love our hatch sound machine. We bought it right before having our daughter and it has been amazing for helping her go to sleep and stay asleep. Also the fact that you can control it from your phone through the app is a huge plus! I always switch it from the music to rain once she is fully asleep from the app. She also loves playing with it because the top has a touch function and changes colors and sounds when tapped :).
The app can sometimes have trouble connecting or be a little slow. It’s also a bit inconvenient that it can’t remember your internet network after you disconnect so you have to fully connect again and enter passwords. Can be annoying if you are taking weekend trips for example and always needing to reconnect when you get home. The chord also is a little finicky and has to be in the exact right place plugged in or else it won’t charge. I wrote hatch about this though and their customer support was amazing and offered to send another chord right away. Overall would still highly recommend because it’s been great for our daughter but definitely has some room for improvement.
