Student Loan Refi question

Hello! I currently have 12,500 (6% int.) in student loans which comes out to 220.39 I pay a month. Credit Karma recommends I refi my loans with a company that will offer me a lower rate which will lower my payment to 114 a month but extends the term out to 120 months. In my current situation, I will finish paying my loans in 5 years. Does it makes sense to refi? Thanks.
