Question: I got this book as a gift and was very excited to open up the package. Unfortunately, it's a total disappointment. The author obviously did not do any research on her topic of time travel (which seems so simple in theory and makes it sound like science). She used some words that made no sense, such as:"In fact, my mind is working at warp speed because I'm doing some intense thinking right now.

Answer: Bad review

Question: I purchased this to replace a different pair of earplugs, but they did not fit any better. So far only one side works. They have good sound if you need the volume up high, there is no reduction to outside noise. Maybe someone will invent better, lighter ones soon. Don't bother with these, they're terrible. Sorry!

Answer: Bad review

Question: This is my first review for Amazon. I have always gotten products without any kind of rating or feedback. In this case, however, I'm glad to give an honest review. The packaging and shipping was just fine, the product itself does exactly as it's claimed to! My husband used this before going on vacation with his friends last week. When he came home, it took him less than half a day to recharge both phones 3 times.

Answer:
Good Review
