I had baught an Olight M2R Worrior back in March of 2019. I own a small pest control business and use the flashlight daily. It is starting to show wear and tear, the switch is malfunctioning and is time to retire. Its lasted almost 5 years with drops from ladders, submerged in water, and left in the freezing cold. This flashlight will last. I just ordered a new Worrior 3S and I know I won't be disappointed. As long as you are in business I will be using Olight products for my business. Olight is durable, reliable, and reasonable priced product. Thank you.
