I'm glad to have found this thread. I realize it's an older thread, but I thought I'd check in, anyway, to see if any others may have comments they'd like to add, about their experiences.
I just purchased an MX25L3C (6 Nichia base version), through EagleTac USA, which was on a great sale, that a fellow EDCer told me about (She purchased their 6 XP-G2 version). I was so excited about it, I placed my order, as soon as I could.
Then the light arrived, and things went downhill, from there. I, first, had to clean the insides (the threads were filthy and the contact points were fairly dirty, as well - as if the light had been previously used. This didn't help. I have been unable to get the light to do anything, other than turbo and strobe modes. Twisting/loosening of the head does nothing to change (lower) the outputs (starting with head, tightened). This really saddens me, because it's a very nice light, with a beautiful tint, in a nice compact form factor, for its output.
I first used a set of XTAR 2600 mAh ICRs, then a set of EagleTac 3100 mAh ICRs - all fully charged. It made no difference.
I own other EagleTac lights (D25LC2, P20C2 Mk II, T10LC2, and I had a TX25C2, which I lost....:-( ), so I'm very familiar with how the twisty interface should feel, and the amount of head travel that should occur, before modes start to change, on one of their lights. Even with a very slow, full half-turn (loosening) of the head, nothing changed.
I called them up on the phone, after I received the light, after having spent the better part of an hour, meticulously cleaning it and testing it out, with no luck. It was nearly 5:00 pm., and I noticed a note on the website that said they would be out of the office between the 13th and the 17th..., and they would be shipping out open orders on the 18th; so I didn't expect a call back immediately. I'm sure they're sorting out their numerous emails and voicemail messages they must have received over the weekend. I have no problem with that.
I've also left two messages through their website messaging system.
Earlier this afternoon, I called them up over the phone, hoping to get through. No luck. I left my second voicemail message.
Right now, I'd just like a light that functions properly. I just want to get this resolved as quickly as reasonably possible. It's a lot of money (for me, anyway), and I'd hate to have it tied up in a not fully-functioning light.
The light was on sale, and it's quite possible that they no longer have stock of this model. If that's the case, I'd just like a quick refund, after going through the necessary RMA/return process, and hopefully with as few headaches as possible. I am also hoping not to be stuck with return shipping, considering I just received the light, and it's not properly functioning, right out of the box. If I have to pay return shipping, so be it. I wasn't very happy to see such an expensive light packaged in a soft plastic envelope. The EagleTac box was packed in bubble wrap, but that just doesn't sit well with me, considering it's such an expensive light. I'd have expected it to be in a proper box, and with the bubble wrap.
The fact that it came in, with those filthy threads and dirty contact points, made me believe that this flashlight may have been a customer return, or that it had been used, previously - possibly as a demo...? I did not expect the threads and contacts on my brand new light to be this dirty. It really surprised me.
Anyway, I checked in here, looking to see if any other folks had positive or negative experiences with EagleTac USA, with any of their purchases.
It'd be nice for someone to pick up the phone. I'll try again tomorrow, before I have to leave for work that afternoon. Hopefully, I'll get through.
