Ordered a nitecore EX10 a week ago, and it turned up in the mail yesterday....but i was a bit suprised when i saw that they accidently sent me a Extreme instead. Now i have this dilemma....i wanted a small light as my primary EDC, and even if the Extreme seems to be a great light, it´s substantially bigger! I don´t know what to do, keep the Extreme or send it back and get the EX10?
