Query: we can't go a night without it

I was skeptical about this at first, but it turns out to help us sleep better than ever before. We've lived in a few loud apartments with late-night noisy neighbors, leaky rain gutters, and stairwells next to our bedroom, but this Marpac sleepmate helps keep all of those quiet.My wife and I have tried sleeping in hotels or other rooms where our sleepmate isn't there, and it's been a tough night of sleep. We don't think we're dependent on it, but people in hotels can be loud, and B&B;'s have creaky floors when you get up to go to the bathroom.I used to have earplugs to help me sleep, but after those got lost I still found myself waking up at ever sound. I'm not even a light sleeper, it's just living in an apartment is loud.All in all, a great product.
