simple and straightforward does the trick
We purchased this item to use in my son's room to generate white noise while he sleeps.  We had been using a small fan but with the advent of cooler weather, didn't want to keep running it.  I like that the unit is very small and simple.  I think that it helps create a 'layer' of sound that helps other household noises and street noise stay more in the background.  So far, so good.  It turns out we have a friend who has the same model and has been using it for years.  We hope that ours will be similarly durable and long lasting.  We plan to even pack with us for longer trips!
