What more can you say? LEDs are very bright. The many light modes need not be forcibly. Therefore it would have been thoughtful, that you do not always have to switch through all modes on and off. Better again, press and hold, so that the part is one or just out. And the modes used last is retained. Feel cheap. If one the thing down (happened to me twice on the road), the housing jumps up. The batteries jumped out. But it was about nothing broken. Simply reassembled (as when changing the battery) and you're done. Have now even scotch tape wrapped. Mailorder me but has also tasted just under 3 euros the lamp. Since you can not expect much one. The lamp is mounted with me on the bike. For more than 3 months in use. Seems to be splash proof. Therefore, 4 to 5 star. As I said, cheap cobbled together, but inexpensive.
