For some reason these earphones produce an almost constant buzzing when I have them on or turn the volume up. Even at max volume. Very annoying. I've gotten two sets of those cheap chinese junk ones. They're worth it to spend just a few bucks more. You get what you pay for. Spend your money wisely folks. These are a total waste. I'm very unhappy with this purchase. Don't waste time and money. Get something good. That's where I've ended up now.

I've had these filters for about a month. I can notice an improvement in air quality, but no changes regarding our overall health. However, we use the filter everyday, so it's not like we're breathing cleaner air. This isn't to say that there aren't other better ways of providing clean air, though. Still, it seems worth it and we love being able to feel good knowing that we're doing something healthy with our money when using this..

Ex Output:
Good Review

If I were to pick a single thing that the movie has going for it, it would be this. In this world, the citizens are no longer all on Earth. Yes, you read that correctly. Earth gets destroyed by terrorists bent in destroying it. The United States of America is now divided into five sections; Earth, Mars, Mercury, Venus, and Pluto. They each have their own leaders who work with one another as they hunt down and kill terrorists.
