    "So good...love it...Extended battery life better than previous generations...This is definitely a good charging unit the only reason why I didn't rate it 5 stars is because it does add a little extra weight that's the only thing I don't like with phones or if they're heavy but besides that with the charging and everything it works great just adds a little extra weight that's the only thing that I don't like otherwise very good that unit for charging"
