Review on HIFESON 21V Automatic Functions Professional by Jamal Gignilliat

This is a really good idea but the product lacks perfection. The product does not work as described in the tutorial video. When you press the power button to put the gun in power mode, indicated by a flashing LED, the gun will not automatically reverse as shown and the rivet will be compressed so hard that it is very difficult to remove it from the set screw removed. In addition, a fully charged battery is completely discharged after just one use.
