My Samsung charger had gone out and the OEM was ~$20 and the best I could find on a knock off was $5+ until I saw this thing. I assumed it would be a piece of junk if it arrived at all as the total including shipping was under $3. While the specs do not match the original (large voltage range as opposed to a fixed OEM voltage) it does plug in and charge the phone. I may be ruining the cell or the charger may give out tomorrow and if so will post a follow-up later, but for now this thing is working and I got it in the mail 3 days after ordering!! If it continues to work I will be ordering again from this place.
