I had a Klarus Mi7 in olive that was less than 1 year old. The engine died and I contacted Klarus to begin the warranty return. They instructed me to go through the dealer where I purchesed it (Battery Junction) which I did. That was nearly FIVE months ago! I have sent many emails to Battery Junction and they say they're just waiting for the replacement from Klarus. My advice to anyone considering buying a Klarus would be NO!
