I ordered the wrong charger for my sons laptop and when I emailed to ask if I could return it they said yes of course. But the best part is I emailed at night and they responded right away. They walked through what I needed to do to help them figure out what was the correct charger I needed. They were awesome! They figured out which one I needed, they sent it right away and now I can say. My sons laptop is up and running. Thank you Chargerbuy.com!
