I've only ever used these... one on my rifle and one for spotting never failed me but I don't get out as much as I'd like too so I guess it comes down too circumstances if I'm honest and I was out 4 nights a week I would probably invest in a good quality torch also be cautious there's a lot of fake 18650 battery about that are very dangerous mine come with a insert that converts it to take 3 triple a,s. Arb be safe
