as to the goncz m3, this is a little mini-review as far as build and modability goes.
bart sent me his goncz m3 for modifications, which it is undergoing now. i wasn't able to test the light in its stock form, because i'm out of batteries
the build quality was surprisingly good, it felt solid, and everything was machined very straight.
the only machining problem i saw was that the tailcap knurling was horrible, it was gouged and several knurls were missing, the damage took place before the annodyzing, so i know it happened in the factory.
i'm not sure what contractor he uses, but i'd probably consider them if the cost was decent. the machineshop evidentally has some very precise equipment...too bad its' being wasted on such poor designs.
while the machining is good, the design is quite honestly horrible. the tailswitch is a complete joke! i've seen better tailswithes on $10 asian lights!
it a momentary, with a twist-on for constant. the momentary action is horrible, and i wouldn't trust it in the water.
the tailswitch is currently undergoing modifications. it's a piece of crap.
there was no spare bulb, and no room for one.
the orings are
horrible!
i could make better orings out of
cheese!
they are orange and extremely susecptable to damage. you need to be careful when handling them, because you can slice them with your freaking fingernail!!!
they're also way too large in most places. smaller orings with shallower grooves would have been a
far better choice.
the o-ring on the head doesn't even engage!!! drop it in a bathtub or toilet and i'd expect it to fill up faster than the titanic.
the focusing mechanism is quite nice. it could certainly be improved, but it works pretty well. i was actually surprised that it worked as well as it did.
the bulb mechanism. this is a joke also. the bulb is a bi-pin, and it plugs into a bipin-pr base converter bulb. the converter bulb is held in with a snap ring, and was a pain to remove. this was a very poor design choice. again, it was consistant with some cheap asian lights i've seen. maybe worse.
the reflector. the reflector is crap.
it's not nearly as reflective as other reflectors i've seen (surefire, pelican, streamlight, mag), it's horrible!
it's also waaay to shallow to work well.
i held the reflector up to another 5w mod, and only the very top of the reflector was utilized.
i won't go into details about the modding aspect here, but i ended up machining the reflector into a ring that will hold a
pelican m6 reflector in its place. the pelican m6 reflector is many times superior.
the annodyzing is decent, but not great.
it's type 2, very inferior to the finishes available on surefire and arcs. the head has a purpleish tint, compared to the blacker body.
it's easily scratchable.
knurling. the knurling isn't that bad, but there are 3 different kinds of it! why not use one knurling style the whole way through?
as i said before, the tailcap knurling is crap.
this light has a boroflo
at lens, though it isn't coated in any way. it's held in place by a reflector that is tightend onto it from the back with a spanner wrench.
overall, i'd say that this light is somewhere between a $10 ebay asian knockoff and a maglite.
when i first recieved it, it felt pretty good in the hand. i at first thought that it would make a very good mod canidate.
after disassembling it i realize that such was not the case.
i thought of the focusing mechanism, the decent shape, battery configuration, and decided that it would be a good mod host, but then i thought about what makes maglites a good mod host.
they too feel solid, have a good focusing mechanism, and offer battery optsions.
the difference is that mags are cheaper, their orings are better, their switches are better, they're reflectors are better, and they're way cheaper.
machining: 8 out of 10 stars
cost: 0 out of 10 stars
looks: 7 out of 10 stars
designing and engineering: 1 out of 10 stars.
in it's stock form, it's a complete pile if sh*t.
after modding it, it can be a decent light, but modding is going to be a
huge pain in the azz. i've already started machining the tailswitch and the head and the reflector, and i ain't done yet.
i would recommend almost any other light on the planet before this one.
