A sound machine is something I would never think to buy for myself, but if you're a light sleeper like I am, this works wonders! This 6 sound sound machine from Big Red Rooster has been the sole reason for me getting such good sleep this week! I'm a light sleeper, so I typically have to sleep with the TV on as background noise. Not anymore! The sound machine saves me money on the electric bill since I no longer have to sleep with the TV on. I love that it can be powered by batteries, or by ac adapter. It's super compact and lightweight, making it great for travel. The optional sleep timer also comes in handy so you don't have to run it all night if you don't need to! Everything is labeled and it's so simple to use that I didn't even have to open the manual! All 6 sounds on this sound machine are super soothing and relaxing! I never thought I'd own a sound machine, but now that I do, I regret not getting one sooner! [This review was collected as part of a promotion.]
