[Q]: This cookbook isn't simple, as claimed. I bought it for the photos and supposed ease of recipes, but the truth is most of the stuff in there is flavorless and more difficult than necessary. The most frustrating part, aside from it not being recipes most people really eat, is that the 'simple' recipes require having other recipes made before-hand, and then lists them as an ingredient. I sent it back.
[A]: negative

[Q]: I use my mobile phone constantly throughout the day for work and need headphones to so I can have both hands free. These headphones are amazing, comfortable, and a great buy.
[A]: positive

[Q]: This product is one of the few things that I could see a difference in my acne with. It definitely helped with texture and smoothing out my skin along with evening out my skin tone from hyperpigmentation. It did not completely change my skin but it definitely helped a lot. A little also goes a long way so it is well worth it!
[A]:
positive
