Good quality product. Fits nicely on the iPhone 4s. The screen protector has this weird rainbow effect. But other than that it does what it's supposed to. I would buy a similar product from Tech Armor.
Good Review

I have purchased this product before and it tasted fine, however, the last two times, something was not quite right. And sure enough, my third container also left an awful metallic taste behind it. I gave one bottle to a friend who had similar problems, then decided that we should throw them out. That is what I did. Too bad because they are good tasting.
Bad review

This product is so disappointing. We just installed the first one and after about 2 weeks some water started to leak. After talking with customer service, they sent me a new one. But same thing happened again at 4 weeks. In addition we have had trouble finding replacement cartridges for this product. And worst of all it came in several large pieces. It also comes without instructions. Which really does not make sense since you are using it only as an aerator.
