I received a charger from ChargerBuy.com less than 5 days after I ordered it. That charger stopped holding a strong enough charge for my computer within less than a week. I emailed ChargerBuy.com the following weekend. Daisy responded to my email promptly asking me different questions to try and figure out the problem. After a few emails back and forward she sent me a new charger and let me keep the old one. My wife and I have been using the new charger for nearly a month now with no issues.
Customer service was very good after a few emails back and forth. I would definitely recommend this company and use them again!
