The GoPro Hero 3+ batteries are supplied in a small cardboard packaging. A German manual is included. The batteries are processed very clean and of high quality and do not differ in design from the original.
When inserting and removing the GoPro no difference to the expensive original battery is determined. The tab for easy removal from the GoPro is also available.
The technical data are given as 3.7V / 1180mAh and thus the original GoPro Hero 3+ battery comparable.
I am satisfied with these two extra batteries. The price is absolutely favorable.
