Query: Great White Noise Machine

I am a light sleeper since having my children and this noise machine has been my lifesaver. Before I got it I would always run a fan at night, even in the Winter. It made my husband nuts. I bought my kids a white noise machine with a night light, and finally figured I should have one too. I like this model the best because it can run all night and has a sound I like (wind). My only complaint is that it's not quite as loud as I would like, but I tried a few different machines before settling on this one. I actually just ordered a second one since my original one stopped working after 2+ years and after we got back from a road trip where it was in a duffel bag and got kind of beat up. I don't think it was because of poor quality.
