Reviewed by connortsaiI wish companies who make bike lights and computers would stop using the "tool-less" setups that require the use of coins to tighten the mounts. Other than that complaint, there's nothing else. The light can be removed from the bike and be latched onto your pants or bag, if you desire better road visibility. It's not really usable as a helmet light unless you place it on a strap. I've had mine for about three years and still is bright, even though I may have dropped it a few times ;]
