To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyzes reviews to verify trustworthiness.
start with the quality, the threads are cheaply made and you need about two or three of them to do all your teeth. other thing is the edges are to sharp i have blisters all over mouth cause of that. Not recommended at all.
Bought these for my wife. She likes to keep these in her purse. I personally like the regular floss w the long roll of floss. She rated these at four stars and said the the floss didn't break off the plastic holder.
I am very happy she is satisfied and rated them a four. Especially as I bought 3 bags. This ought to last her a year or so at least w the three packages.
