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..

This coffee cup is just about the perfect size. I enjoy drinking an espresso and a large mug will not always fit. So while this product didn't solve my problem it came pretty close. The color of the chocolate brown adds to its classy look. It only gets 4 stars because you have to hold on tightly when washing or any liquid from your beverage will spill. A great buy though for anyone that wants better tasting coffee!

This has to be the worst printer I have ever owned. If you print color there is no way of getting it right. The cartridges are so expensive that I'm out all my ink. You can not use other paper with this printer. It won't allow it. It prints very well when new but if one cartridge runs low it's useless for anything or just says wrong part number. This is by far the worse investment I've made on Amazon.
