User Review: Princeton Tec EOS
Price Paid: US $41
Brought it for a six day trek through the mountains in Malaysia which ended up lasting seven days instead. It is really bright and great throw. I could easily luminate more than 20m away, more than necessary for most applications.
A set of new alkaline batteries lasted throughout the trip, and is still going strong. Low setting is adequate for most campsite activities, while I used medium for night treking. High setting is hardly necessary at all.
Used it in the rain, and it proved to be really waterproof. I didn't even need to open it to dry it out. Materials used feel solid and rugged. A little heavy for its size, but I don't think anyone will notice the few grams more.
Some nits are that the edge of headband developed a wave, like the collar of a T-shirt that's gone through too many spin cycles. The hinge is rather loose, and although it has not shifted due to head movement, I feel that it may be easily worn out after regular use. The lens also got scratched, though I can't imagine how. A harder plastic or a scratch protection film would be great. Or maybe a more recessed lens. Lastly, the beam is a pretty tight spot. I wouldn't mind sacrificing a bit of brightness and throw for a wider and brighter sidespill.
