I bought an Estrela last September. I starting having issues with it just after New Years. It intermittently turns itself on at the "dimmable" brightness, even if it is locked out. I called Nightreaper and left a message. They never got back. The website doesn't provide a CS email address. I PM'ed Chuck, and he was super helpful. He got in touch with Ken Good on my behalf and exchanged email addresses for us. I emailed Ken directly, waited a month, emailed him again, waited another month, emailed him again, waited another month. Two weeks ago I visited the website again and sent an email to the sales email address listed there, no response. It's been just over 3 months now since initial contact, and I still haven't gotten any semblance of response from them.
I feel terrible, because I'm sure Ken is a great guy, Chuck has had awesome things to say about the light and the people, and Chuck has also repeatedly tried to get in touch with Ken on my behalf, which is really above and beyond on his part since he has no interests vested in this. Above all else I hope the people at Nightreaper are safe and healthy.
However, the time has come when I really need a duty light again, and I can't just wait around forever sitting on a broken product with no CS. Moreover, even if it were to be magically fixed now, I don't know that I can trust a product for serious use when the company backing it is so hard to get in touch with. Honestly, had it not been recommended by respected PF people, I think anyone else in my position would have long ago concluded the company and product were crap and non-starters. Personally, I'm still holding short of drawing that conclusion.
Having said all that, what alternatives are there for awesome uniformed-patrol duty flashlights? Must be rechargeable.
