When I placed my order, you asked me to provide you with feedback on the Olight M20 Warrior 2010 Flashlight. I have now used it a bit & must agree that this the most efficient & bright flashlight I have ever had the pleasure to use. It is well built & the fact you can select the intensity of the light power as required if a great & well thought out concept. Also, from what I have seen on the Web, some dedicated testers also recommend it highly as well. My thanks to you for having selected this particular product for sale to us consumers .!!
