This is the 2nd car adapter I have purchased from this seller. The first one worked---for about 3 months. I am hoping it was defective. Received the new one and it is working great. Hopefully I will get more longevity out of this one.Edit: Well the 2rd and last adapter I purchased lasted almost a year, then broke for no reason. Honestly, it's such a pain to keep buying these that I am just going to shell out the money for a name-brand charger.
