content: I have used this headlight for weeks now in hunting and camp situations and found it to be exactly as advertised.It is very good quality and the run time is nice. I use it mostly on low and it lasts very well with the 2-AAA batteries it uses which by the way are another reason I tried this in the first place because AAA are common and available as well as cheap to use. The Enduro is awesome for the price and the high setting is pretty good for about anything within reason for a light of this caliber. I can't speak of its waterproof design but it looks like it will take a drenching with no problem with the oring seal it has in the battery compartment cap.You can't go wrong for the money.
