This product has already impressed me. I bought this razor just a few days ago and have used it multiple times already! It does not pull or tug like other razors I have used. I am a big fan of the multiple attachments that come with this razor, the nose hair attachment is one I will use the most!

This book has a interesting storyline but I found this book about as much fun to read as a textbook. Reading it was like slogging through a bog - it just didn't flow. If lack of proper punctuation and misuse of words (their for they're, your for you're, etc.) annoys you, don't bother with this book. I did persist until the end because I wanted to see how it played out. Guess what? There is no end. Everything is left up in the air, nothing is resolved! Ugh!

This product stopped working after about 2 months, which is of course out of the return policy. When we plug it in, it doesn't heat up and there is a red flashing light on the controller. We had a similar blanket that lasted for several years before being destroyed in an unfortunate accident. We thought this would be a good replacement, but it did not turn out to be.
