The 2 stars are for reliability, because the product is effective enough, see other comments It worked very well since 30 November 2014, and yesterday down buttons no longer work, only the on / off button. Other more, less and turbo no longer work Information for this product is guaranteed for 3 years, I saw a person who after five months threw in comments !!! After telephone contact with Amazon we must do with babyliss by phone by paying toll (6 cent per minute) !!! Babyliss SAV refers us to Amazon for a replacement product because the product can not be repaired, so it's necessarily an exchange against a new one. Amazon also offered us a refund so we had the choice between 2 solutions. Amazon thank you for your willingness to help your customers. We decided to give a second chance to this product, so an exchange against a new, Amazon was very responsive to resolve this issue.
