This product fulfills its purpose fully: it gives me on a wheel without Dynamo a secure, highly visible light including red reflectors to the rear, without attracting attention as a battery light, as it visually indistinguishable at first glance from the dynamo version (battery lights are loud Admission Regulations actually just additionally permitted, except in racing bikes under 11kg - but that racing under 11kg has a porter?). Since the lamp is attached with screws to the rack (both conventional drill hole spacing 5cm and 8cm fit), it is also not as prone to being stolen as the whole alternatives. Stable is thus also mounted, I do not think I'm going to lose in rough and underground, as the rear light, which I had previously installed. Operation with the switch occurs to me much easier than with small lamps with fiddly buttons, some of which were no longer operated with gloves.
Very good, I like that it is powered by two AA batteries, thus I have a single battery size for front and rear lights, which simplifies the carrying of replacement batteries for me. It is helpful in the context, the battery status indicator, realized with a small colored LED which is visible from above. For me a top product, the price is relative so clearly and it is very cheap value.
