Well here are my thoughts. I’ve had mine for a couple of weeks. Performs awesome. I really like the length of a 2 cell 18650 battery tube. 2 minor issues- there will be no neutral tint available per Wowtac. Not a huge deal, I’ll do it myself. 2nd, that great handleing battery tube is 1/4 (6.35mm) to 3/8 (9.525mm) too long. Flat tops are a no go, magnets help. But I’m sure Wowtac’s intent is for you to buy their batteries which will set you back another $30 if you buy the 3400 mah version. Now you have $70 invested into this light. If you are not a flashlight hoarder and you are looking for that one good light this one may not be the one. At $70 to $80 price point there are a lot of other options. A spring on the head instead of a direct contact button may have solved this issue all together. This is just my thoughs and OPINIONS. Just something to think about before you purchase. Overall I do recommend this light if you are prepared battery wise. I may buy another one just to make one in a neutral tint.
