Easy to install and remove (which also makes them easy to steal so be sure to remove them if you leave your bike in a dodgy area!). Very easy to pair the lights with the remote. Just a few remarks: unlike the turn lights on a car or scooter there is no way of knowing if these are still on or not, there is just a quick flash on the remote when you press the button. Usb cable allows to charge 2 lights at a time but it would be nice if there was an extra cable so you could do all 4 at the same time. There is a mode to flash red lights in the night but it would be nice if it could flash green in the front and red in the back to avoir confusion from oncoming traffic (there are green leds already inside that light up when the batteries are fully charged). We’ll see how they stand up to the reliability test (especially under heavy rain!) but until now I’m very satisfied.
Arrived very quickly and the goods were very good.
