I bought this charger because my apple charger decided to die not even 2 years in. Just purely didn't charge anymore. I purchased a different charger a few weeks back, it charges just fine but once the laptop is charged, it keeps sending the signal to charge more, which is really annoying for the macbook to make the charging sound every 10 minutes. I replaced that charger with this one, and it charges perfectly and doesn't send the signal to continue charging past 100%. Love it! Recommend!
