But otherwise a good lamp, easy to apply and really very bright. The rear light is small but good, just more suitable for road bikes because it is attached to the seat post.
Enclosed batteries are not rechargeable batteries. Battery and charger must be purchased separately.
The case looks rather cheap but convenient for the price category you probably can not expect more. Nevertheless it makes a robust impression.
I do not regret the purchase; but find misleading that with StVZO approval on Amazon and the front of the package is advertised and is mentioned "only on road bikes weighing less than 11 kg use" only in the small print on the package back the restriction.
