I have purchased a lot of torches in the past and they never live up to their claims. This torch is actually one of the brightest torches I have ever used. You get 3 adaptors for it as well so you can use 18650, 1 AA or 3 AAA batteries to operate it. I suggest using the 18650 batteries as it is a lot brighter. The focus function isn't too tight or too loose, it's bright, on/off button is firm, has all the settings you need and very well made.
