[Q]: 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..
[A]: Good Review

[Q]: I bought this camera at the end of May with high hopes, and it surpassed my expectations. I'm no photography amateur, but I've managed to capture some pretty cool shots over the past couple weeks. Here's what i love about it:-The shutter lag on slow moving shots is incredibly minimal, which makes me even more impressed.-Even in fully automatic mode (auto), I was still able to get a number of great shots.
