Answer: negative

Question: I bought this for a friend who planned to travel outside the country. I told her it was to wear in case she was robbed--in the event a loss but not a GREAT loss. It is so pretty she was worried it would invite a robbery! (She wasn't robbed but really enjoyed wearing it.)

Answer: positive

Question: My dentist recommended these tuft brushes to help clean the deep grooves in my chewing teeth (molars). Most regular toothbrushes and even electric tooth brushes do not reach deep enough, which led me to have lots of cavities. It also is great for reaching behind my back most teeth. I use both regular tooth brushes and this brush to clean my deep grooved molars. So glad I found these in economic 3 packs, so worth it...

Answer:
positive
