They last long and seem to have good quality. What I love about these is the mounting and dismounting mechanism of each light; the rear light can easily be removed like a quad lock, and the front light has a tab you push and it slides out. They also include a cool USB-A cable that branches out into two USB-C connectors. Perfect for charging both lights at the same time, using the same usb-a port. Never knew those even existed.
Arrived overnight in good condition. All parts in pkg. my husband had no problem putting it on his mobility scooter. The headlight brightness is very good. The back flashing red light gives you several options of blinking sequence. The charging cord included is a split cable so you can charge front and back lights at same time. Cannot give information on duration of charge as he has had it going for an hr, off and on, and not lost its charge. Price and quality gain recommendation.
