    I couldn't help myself, and retrieved the pill from the trash. I sent it to 4Seven today, with a cover letter. I explained that I probably voided the warranty, but I'd be happy to buy a new pill when a revised model becomes available. If nothing else, postage was only A$2.70. To post the whole thing back would have cost more than the P0's purchase price.

    I will let cpf subscribers to this thread know the response in due course.

    If the PO was offered in large marts (Office Depot, Home Depot, ..) Foursevens could sell hundreds of copies in no time -- that is my strong believe.

    attractive tiny size, no competing product available (DQG Tiny III, China shipping, more expensive, not available right now), gift box packaging, reputable American company.

    The PO has the potential to become a legendary bestseller as could be indirectly seen by the high number of views (500,000+ views, this thread!!!) -- it just has to be flawless and robust. Then word will spread!

    I would think that Foursevens company is more seriously concerned by Surefire's attack (lawyers) so we cant expect a physically revised PCB design anytime soon.

    Products evolve. That's normal. You have seen the Zebralight SC600 evolve, havent you?

Would i buy another one if mine went "poof beyond repair" ? yes, no doubt.
    Well said, Jorn. Along those lines, wouldn't a little ball of aluminum foil wedged into the ring help solve the Eneloop problem? I'd try it if I had some (only AA 'loops).

The PO would only be slightly longer, and as small as it is already, that wouldn't bother me at all. Then it would work with any cell you could poke in it! I was planning on running my Eneloops, and the fact that I can't, is crap! Just my humble opinion.
    Hi Mrlysle,
    I agree with you. It would only add ~0.3mm to 0.5mm in total light length. The only problem would be that they would need to retool and redesign the head. If they just increased the pads height, that would only leave about 3/4 of a turn to keep it water tight in the off position using the current o-ring design and components.

    Hi Geoff,
    I had suggested a magnet here. I would not reccomend tinfoil as it could spread out and make contact with some of the exposed legs of the IC's and because it would be free floating in there when the light was in the off position, you would not know if it is still centered on the battery annode.

    Mine worked fine with a small qtc pill on top of the nipple, so a ball of alu might work. If the ic is alredy torn up, the alu ball will only make it worse. Im a bit sceptical to a ball of alu foil, might be deformed and chewed up, pices rattle aroud and short some legs or something.

    It would only add ~0.3mm to 0.5mm in total light length. The only problem would be that they would need to retool and redesign the head.
    Yes i also think that would be the simplest and cheapest fix.

    Jorn,
    IMO, I think that redesigning just the Pills PCB would be less expensive since they already have a vendor they purchase from and it wouldn't require redesigning the body or any retooling.
    I can not say MO is 100% true, as I do not know the costs of the redesigned pills PCB and components or what the cost for additional retooling and materials is, just that it would be easier and seamless for Four Sevens to impliment.

    I think the p0 pill and the dqg pill are bought from the same company, they look almost 100% identical. I remeber there was a link to the dqg pill somewhere in a dqg thread here on cpf. (Someone was talking about it's heatsikig and posted link for the pill alone). I don't think it's easy to make a company change it's products all that sudden, unless your the only customer for the product. Im speculating on this one.

    I agree. The p0 is only 0.5mm away from greatness. I don't think it would be impossible to redesign the board with surface mount components (ICs with legs are not just Y2K, they belong in museums). Surface mount components can be assembled by robots, making manufacturing even cheaper than poorly paid workers in sweatshops. Maybe 4/7 could go to a US company and order a batch of circuit boards for the p0, with the knowledge that they won't steal his design.

    I'm having problems with mine. Flashes bright before turning on to high or low mode. Sticking a piece of foil or any other type of band-aid to make a new light work, IMO, is unacceptable. I would like this light if it worked properly, but it doesn't.

    Hi. Can I assume your engineers will work out a solution for next generation P0's only?

    I understand the " Not everyone is having the same issues so we're not going to do a recall " statement, but what about the customers that do have an issue with not being able to use eneloops and other NIMH's because of IC interference? Will you consider recalling and replacing those units? I'm currently using the provided Duracell instead of NIMH because of the IC problem in my sample.

    The Preon P0 is definitely .5mm away from being a perfect little jewel....Thanks for listening.

    My P0 was doing something similar. I followed SelfBuilt's advise on his review... temporarily removed the foam and tightened the pill using the blunt edge of an exact-o knife and it works perfect now.

    Hope that helps.

    Yes I agree. That is only one of the problems with High Resistance opens. The alluminum pill screws into stainless steel, The contact that the pill makes can get flakey. I choose the same fix on one of mine. Additionally I took the pill out, carefully lightly brushed the pill's threads using small wire brush, Cleaned the flashlight heads' threads, and applied a tiny bit of No-Ox(DeOxit is simular but much thinner mixture), and carefully screwed the pill back in. Caution, do not over tighten the pill. Doing so will push the lens's o-ring out the front.
    The other two areas of trouble are the bottom of the battery tube, and the flashlights threads. If they get dirty, they can also make the light act up causing inconsistent switching trouble.

    That's great news Kilovolt!! Glad it worked out for you. Don't put any other batteries in there or you risk fryin' an IC through abrasion by those fatter nippled alkalines and nimh's.

    It's there now. They are still tweeking the site. It won't be totally live until sometime next month. Some accesories are there now, some batteries, some first generation limted editions that will probably be part of an archive section, but the dang Zoom feature is still stuck there blocking the navigation buttons at the top when you select a light to look at. Click zoom, click close, and it's gone. Hope that gets fixed

    any backorder updates on new Preon P0 hardware revisions or improvements?

    the new improved DQG AAA version (limited edition as always) is already available for pre-order on their website (DQG Tiny III, release data 10th April) and since it's the direct competitor to the Preon P0, i would really love to hear some news now, thanks!

    I have done about every fix I can imagine on mine but on Ni-mh it still flickers every other time it goes to high mode and there is a pre-flash the first time it comes onto moonlight mode after being off a while still too. I'm holding off on sending it back though as it works so well on Energizer Lithiums, and is so light with them in too.

    Any news or updates on the Preon P0 front? Were there any changes in the original design? Users had reported problems with Eneloop cells, loose magnets, mode skipping, etc.

    Meanwhile the DQG AAA is out in its 3rd revision ("DQG Tiny III", version in Stainless Steel ©2012) with little (but significant) improvements in the design, see CPFMP Dealer's Corner, and thus becoming maturer and maturer cada vez mas. still not perfect (i prefer the P0's tail design!) it seems to beat the P0 (old design) in many ways, except for warranty and price.

    Waiting for the P0 to catch up and become maturer as well thanks!
