good battery, nice throw of light one straight and other down facing. lasted me a full night BRM at 2nd level of brightness with both bulbs on. I have fitted this on garmin mount. the smart day feature is great as when daylight is enough the brightness reduces automatically. Quite Sturdy. fast charging thanks to usb C. Only problem is that you have to be careful to store it in a bag with other items as it accidently turns on quite a lot. so do use the lock if storing somewhere where buttons can accidently get pressed.
The light section is good. But the holder is useless. It is very feeble compared to the weight of the light. The options for fitting the holder are limited. In fact it doesn't fit properly on a thin handle.
It is a good light for cycling in trails. Works well as claimed. For city commuting, the lower beam (Right side) is recommended for oncoming traffic.
This is one of the best lights out there. Long rides or short rides this light takes it all. Go for it!
It is very useful for early morning/night rides. I am able to complete 600 kms BRM comfortably. I recommend this product.
