I returned it as soon as I received it. Give something more and get something better so that you don't cry over your iPhones.

I am not very convinced that it is original, but it must be OEM, meaning from the same factory as the genuine ones in original packaging or something like that. Generally, it works just like the genuine one that I lost. Some people say that it gets warm... it gets warm just like the genuine one. Overall, everything is okay. The store never communicated with a tracking number, etc., it arrived unexpectedly.

When it starts charging, it raises the temperature, resulting in burning the adapter throughout the charging process

Very good product, with positive satisfaction!!! No matter what cable I use, it works perfectly. Well done guys, good job.

all time classic, small, lightweight, reliable, now it is very cheap, it is the classic charger that you now find as a gift with all iPhones.
The only downside is that it charges slowly (compared to newer, much faster ones) but at least you have peace of mind that it won't damage your phone.
I use it at night to charge my phone on the nightstand while I always have a second one with me in my backpack.
If you don't need it for quick charging (e.g. at a station, at the airport, etc.), trust it for its stability. Just remember that the charging speed (or the potential damage to a phone) also depends on the cable.

It works fine on iPhone 5s.
UPDATE: I bought it again for iPhone 6s, it's terrible. It broke my socket. It showed that it was charging and kept disconnecting while the phone and socket were stationary. After a while, the socket broke.
