Very good. It should be the original one. The heat is not serious, and the volume is lighter than the original one.

It is the same as the original, with the same parameters and shapes, but it is slightly hot to use. It may be the difference between different production places. I plan to use one as a backup, often bring a computer, and have one at home and in the office. It is convenient and much easier to mention. It's safe to buy an original one. Although it's expensive, I hope the quality can be guaranteed later.

The original one is a little too expensive. It's congested and the original battery is bulging. It's too difficult for me..
