Pirate from Youtube gave us this amazing review of the IAOMI Smart4u SH50 Cycling Helmet with LED & Light Sensor.
XIAOMI Helmet Smart4u seems to be super nice , quality for the price is super nice. On the back of the helmet is built in waterproof LED with light sensor, it can be charged by included adpater with USB. After 3H of use I like it , its comfy and makes me feel much more confident š
