Is Armytek a gamble... If it works yay... If not, boo! I understand we all demand instantaneous satisfaction and what Armytek asks customers to do is reasonable. Sometimes it's a simple thing as cleaning the threads or tightening tail cap screw. I understand they need to protect their profits and they are running a business. After you done everything they ask to do, they give you the run around and don't honour their warranty. After whinging in here and through emails, they finally send you a tail cap that you were telling them that was the problem. It takes a month to arrive in the mail and then it's the wrong tail cap. So to me, yes, it's a gamble. Yes, they make nice and unique lights which attracted me to buy their products.
