hey everyone once again im worrying about my baby, i noticed today when i swing the arm it seems to be getting looser, also the brass(i think its brass) piece where the atomizer connects is getting loose also and when switching positions it wiggles a little up and down. has anyone else had this and can yell at me for worrying about such a great product?

No yelling around here. Just take the reasonable questions, comments, observations and statements of experience for what they are. :)

It's normal for the swing arm to loosen up a little bit with use. After mine came back from repair with some upgrades, the swing arm was firm and almost "clicky". After a few weeks it has loosened up some, but still has pretty distinct detents that just have a little more play in them. As long as it doesn't swing free on its own that's pretty normal.

As for the brass connector getting "loose": Most of the time I use at least a 510 shorty connector on the arm, to avoid possible wearing out of the brass connector ... but don't judge a slight "loose" 510 connector too harshly. A little play has its benefits in improved air flow/draw.

For example, I have a couple of tube mods that I really like in many ways, BUT the 510 connector seems to be made to a very tight tolerance. This means that anything 510 does screw in there, but the draw is tighter than any other mod that I have. More than once this has resulted in cartos getting hotter than they should and getting burned.

So, a little "play" in the 510 connector is, in my mind, not a bad thing as long as you respect what it is and what it means and don't try too hard to crank an atty or carto in there to get a tight fit.

That said, if the fit is really sloppy, that could mean that over-tightening has already occurred several times and caused more than the normal amount of wear which could eventually lead to intermittent connections, in which case a shorty extender does a good job of extending the life of the connector.

Hope this helps!

Sadly, my Darwin has stopped working. The screen is blank and it won't fire. I have tried 3 different attys and a fusion to make sure it is a problem with the Darwin. I made sure it was dry. I tried it with an adapter and without one. I have always used a 510 to 510 closed adapter on it to protect the brass threading.

What is the process for getting it repaired? Is there something else I should try? I really wish it would just magically start working.

I bought it in October 2011, so it is under warranty.

Thanks

Just ping Brandon at Evolv:

Evolv, LLC

They will certainly take care of an issue quickly

Yea there are three increments with nice clicks.. The connector on my first darwin wasnt sealed these, this one is.. and the arm its self looks different...

BUmping this pic up for Gnardys..

The new connectors are actually pressed in the arm.. The arm doesnt have inside threads anymore. So that connector is loose? Not the arm right? I would contact Brandon about that.. Let me know if you need any help with it.. Do you still have the order number and stuff?

i got the number and everything, and everything is working fine so no need to send it in, just me being ocd about it haha, its not the connector thats loose its the whole arm, instead of just rotating it seems to rotate and raise a little bit where it connects to the body of the darwin

Oh i believe that is normal. I think it has something to do with the increments the arm moves.. its gotta have some kind of clearance to be able to fall into the 45 and 90 degree position.. If this isnt making any sense then just disregard. Sometimes i dont make much sense. LOL

honestly i think i was just looking to closely at it, during my admiration haha if it works why worry ey?

I'm guessing you still have plenty of warranty time left?
Use it for a while and if it poses no problem then it is probably part of the design.

Having some space/tolerance in moving parts is usually a good thing. They could put springs/bearings and stuff in there to make it feel a little tighter, but that'd just add complication/expense and more stuff to go wrong in the future (both in production and in ownership). At some point they might head in that direction if/when a production process is found that makes it feasible.

Unless you are using really massive/dense quantities of a material, it's going to expand and shrink with different temperatures and types of stress. If the tolerances are super tight, then it calls for much more material (weight) and probably also needs lubricants, which in turn collect dust, etc. So just having a little wiggle room in a design is NOT shoddy engineering (OP, I know you never claimed it shoddy, but some folks out there that confuse precision machining of solid blocks of metal with 'good engineering' have). It's actually smart to have 'tolerances' for temp/motion/stress unless for some reason you need a device of which you intend to shoot into orbit, survive reentry, and be found and used by a mermaid at the bottom of the ocean for 10 years (not that she could make 'vape' with it, but I suppose she might use the battery for something else).
