Not sure what the low mode would be useful for, I use it on medium
Does attach with a ruber band that kind of clips
Good little bike light works well on the country roads I travel on to work An excellent bike light Nice powerful light
Took a very long time to charge, but may be the first charge only (the instrucions are really limited)
Charged up using a normal micro USB charger and needed to cycle back the next day (again in the dark)
Would I recommend this products - Yes most definitely, it represents excellent value for money
