I put a heat sink on all my mods; always have. I imagine it would eliminate any issues you might have.
Still looking at the cuboid myself but just can't seem to Make up my mind. Seems every day I see new posts all over the place with certain issues like finish, 510, amp limit, TC issues etc but I think the battery life is what is really tripping me up. I almost always use the same settings. .2 ish ohm dual Ti coil spaced at 550f and 80w/j and I get a little less than a day most times on my ipv3li
Hi Brent, can I ask where you are getting your heat sinks from and which you prefer? I need a reputable source. My usual go-to suppliers don't sell them.
After a month of day in/day out (including a week long road trip to Vegas) use of my cuboid; the only issues I can confirm are a shallow 510 connection (this isn't a problem if you don't
have to have your atty sit flush) and the voltage meter is consistently a touch off (one side or the other will always read 0.10 volts high while the other is within 0.01 volts; which is contradicted by two different multi-meters which say the batteries are within 0.03 {or less} of one another, and that is with 4 different "mated" pairs and two different brands). I did have 1 (one) instance of the fire button sticking. But it released as soon as I pressed it again and I have never been able to repeat it; even when trying.
The shallow 510 is why I want to try a heat sink. If I can get one that is adjustable I might be able to get it to sit flush and not have to be so careful not to mash out the o-rings on the mod's 510.
Other than that;
no button rattle,
no battery door problems (though it does remain a snug close which is good in my book),
no battery tube issues,
no finish issues (I have the light grey color)(this is as/more durable than any other mod I have owned; I'm not even seeing any wear on the bottom). I haven't used it in TC yet so I can't speak to that. I'm not sure what amp limit concerns you have but mine has performed as expected.
As for battery life, it has performed comparably to my old Sigelei 100w dual 18650 when running same tank/build combos (2 batteries 7-10ml of juice on dual claptons at .4 ohms and 55 watts will usually last me about 16 hours) (I still don't really understand all the contention on this <non>issue).
