The "daytime hyperflash" mode is a beast and the light is clearly visible in the day. A must have if you cycle on busy roads/ highways.
excellent product with a number of modes....and yes expeditious delievery by BOTS
This is a hassle free light u can use with confidence. I have done many long rides on highways and ghats using this. The battery life is gr8. Ad i use it in the strobe mode which is supposed to be 30 Hrs.. I charged it after say 20 hrs of use... didnt risk beyond that... so cannot vouch for the 30 hrs.. Only con i saw is that it tends to rotate a bit on my conical seat post... square and round shudnt have a problem... but its very less of rotation... still visible becoz of its extra ordinary lumens
