This light leaves all the cheap lights like Superfalsh/SF Turbo/Danger Zone/Radbot/All Cateyes etc. in the dust. IMHO, there is no compelling reason to buy them at all. I am amazed how a light this small can be so powerful. For the price, one can get two just for the redundancy. Dinotte 300R is 50% brighter but 600% more expensive so there is no reason to buy it either...
