I ordered one of these lights and received it about 8 days ago and it is Awesome! I would Highly Recommend it to Everyone! The Ring turns clockwise to increase the Brightness Level which is Just like the Rotary Ring Model they stopped making. The entire Head Unsrews from the Battery Tube, or Body.
If it came with a .50”-.75” Longer Battery Tube, it would work with a Longer and Larger Capacity Battery like the 18650 inside the Tube of another flashlight I have. Although they aren’t the same thread pattern?
Has anyone checked their RRT-01 order recently? I ordered on Mar 7 and received a confirmation email. I just coincidentally logged in and had a look at my banggood orders, and it shows as “cancelled”. I never received any further communication from banggood and was not informed they had cancelled my order or provided with any explanation.
Over on CPF, one guy posted about using a Dremel and boring out the slots just a little to make 12mm work. So it wasn’t just the length but the thickness and depth that required trimming.
