I've only slept with mine for one night but it definitely put me to sleep! At first the heartbeat was a little strange to feel/hear but once I got used to it I fell asleep much quicker than I normally do! The design is also very functional so it will be easy to change the batteries and it's also simple to turn on and off as I need it. I think it's definitely worth a try for anyone having trouble falling asleep. Plus, it's a cute little animal. Win-win!
