Excellent for families with kids sharing rooms
I first ran across these at a small bed and breakfast that equipped each street-facing room with one of these noisemakers. I was sufficiently impressed to purchase my own. I just used mine in various hotel rooms on a cross-country road trip with my family. It got rave reviews from my kids, who slept better and longer in a shared room. That trip alone was worth the purchase.<br /><br />We found placement of the device was much more effective than tuning the air gaps to adjust the sound. Sitting the device on the a carpeted floor absorbed more of the high-frequency sounds and resulted in better natural background noise. Elevated on a desk, the sound was a bit more harsh and less pleasant.<br /><br />This is going in my toolbox for family travel for now on, and will be handy when hosting guests at my house.
