Next day delivery after ordering very late in the day, impressive, reasonably priced and so far so good, working well would recommend.
I'm always troubled about buying an off-brand replacement that I was purchased other sites. But I bought a replacement adapter on this site and I started to use it. After some days, I got that it’s a replacement adapter but working as the original. This time, I’m very excited to buy the best adapter for me at a little price.
Pretty simple reason for this rating: It works perfectly and it arrived very quickly, just as I needed. I had ordered this product so that I could use it for a trip, and needed it Asap, and it came just as fast as I could have hoped.
This charger was purchased after my old one was lost a few months ago. While it isn't exactly the same as the original charger aesthetics wise, it has provided me with a much cheaper alternative.The reliability has been good so far, and the construction quality seems to be pretty good as well. Overall I am very happy with this replacement Charger!
It works perfectly with my laptop and it arrived very quickly, just as I needed. I had ordered this product so that I could use it for a trip, and needed it Asap, and it came just as fast as I could have hoped. Thanks seller
