I am writing this review a week after receiving the charger and will update with further use. I have a surface laptop and this charger works the same as the original charger so far away. There is an indicator light to show if it's charging and will flash if it's not charging properly. I had no issues with overheating or tampering with the computer's screen/buttons/trackpad. I also left the charger plugged in overnight with no issues. I don't charge my computer overnight so I can't comment on that. It came with a holdall and paper that says 1 year warranty but they mentioned it's actually 2 years just a typo. You need this piece of paper in order to be able to claim the guarantee according to the form. Overall I would say this is a good product and the wires are very similar to the original just maybe a little weaker. Update: So my trackpad is messed up now and I'm not sure if it's charger related but it could be. When it's charging my laptop, it also makes a loud fan noise. I've mostly had to buy a mouse and charge my laptop when I'm not actively using it. A bit of a shame, but I think all of these surface chargers are the same unless it's the original one that came with the laptop when you bought it. Microsoft also has bad ratings in reviews of the replacement charger.
