User Review: Princeton Tec EOS
Source: bought it new
I was happy with this light for a while. It throws a good beam, nice and bright, goes a long way. The problem is that it leaks. Every time I use it in the rain (which is often since it is on my bike) water gets inside and when this happens - here's the kicker - it doesn't shut off properly, so the battery drains.
To make things worse, I emailed Princeton Tec about this and they didn't even bother to reply.
