Sorry. "poison" is an English slang term, basically I was asking: "what are your favorite day to day mods that you enjoy?"

I totally think every vaper needs a few simple mechs and a large stash of batteries, because well - you never know!

I still prefer the copper SMPL because of the hard hit with 0.33 Ohms.
And the mod is short with 79mm, with atty and DT 103mm.
But the hard hit is gone over the years, oxidation?
Btw.: who still sells good SMPLs?

Batteries: because of the heavy use in tube mods I replace them yearly,
it is just too dangerous to use them in hybrid mods with damages.

And again: hybrid tube mods are dangerous.






I've found performance suffers dramatically with the SMPL mod if you don't strip and clean the inside of the switch frequently (I keep a pair of external circlip pliers on my vape shelf which makes separating the switch a 2 second job).

I don't use my SMPL mods very often these days but I've found that cleaning the 510, switch threads and battery contacts isn't enough as the inside of the switch is prone to tarnishing and needs cleaning just as frequently as the threads

An ultrasonic cleaner will do wonders with copper. Also reach everything that's submerged.
Acids as vinegar will also tend to etch the metal.

I clean SMPL and others with a rotating brass brush (soft and slow).
Between 3 mods I exchanged parts to get better/full "start on" power.
Result:
The problem seem to be the 8(?) to 12(?) notches in the switch.
They seem to make not always the best contact to negative:
you hit the button left side: OK, you hit right side: not OK.
It seems the mod is worn out, too much play between electric parts.
I think I need some new tube mods,
but what to buy?

I'm using Mechs, Semi Mechs and regulated MODs.

When I'm home it's almost always a Mech or Semi Mech.


I recently bought a Digiflavor S Tube MOD SKU 9742594 and I like it.

Yes, brass will scratch copper, so if you have a copper fire button you might have caused too much play between.
(would be possible if you have a brass button as well).
Soft and slow will just make it take a longer time, but you will end up there eventually.
(that's where an ultrasonic cleaner shines, as it does not diminish the metal, just oxide and dirt)

But it could also be that the spring is worn out.

Fasttech used to have replacement buttons for SMPL, sadly not anymore.

But you should be able to source it elsewhere

I dont think you are 100% right, sure cleaning helps.
The current is going from one ore two (better 3 or 4) of these 8(?) notches to battery minus.
When we compare to our normal house fuses, this is a heavy load in Amps (if you dont vape 8 Watts).
Same on battery plus: black spots after heavy use, vinegar will not help.
When the switch (notches to outside tube) is not perfect (or worn out), we have plus Ohms and less Volts.

How did you interpret what I wrote to that cleaning won't help? I wrote that a brush of a harder metal than what you're brushing will diminish the metal. To make it more clear: act like sandpaper and remove metal (it just takes a longer time).

I got the black "welding" spots on the plus pole pretty much from the start, that's normal and will happen as the discharge has such high amperage. Did not notice any power issues from it, cleaning the plus pole with brass would be fine as steel is harder than brass.

While I'm sure this is true of concentrated vinegar the cleaning vinegar I use (schoonmaakazijn) is only 5% to 10% concentration.

I find this especially handy for switches leaving them in the vinegar for about 30 minutes. Then I take them apart and clean them in water with a brush.



@Troepfler, are you using magnets in the SMPL switch? I've made SS springs for mine which imo improve conductivity.

Yes, even a 10% solution of vinegar vill take a very long time to show negative effect. Probably the least destructive method next to ultrasonic.
Would guess that it at least would take a decade of regular cleaning to show the slightest of negative effect.

Using a metal brush of harder or equal hard metal than what you're cleaning is eon's worse.

I have a couple of the older, better quality Simps...(lol)...honestly, they do have a bit poorer performance compared to several other 18650 tubes...could be "alloy" metals/ poor brass/copper quality, and most likely is, as a 18650 Purge mod (for example) has the same basic design, but hits super hard....of course, they use highest quality brass/copper available. Doesn't mean their exorbitant cost is "worth it", but the metal is quality.

I guess the YFTK Vapeware clones are sold out, but that was the best performing 18650/22mm mech tube I have EVER bought. The same atty on both tubes clearly shows the volts drop-off - not MASSIVE, but highly noticeable, especially when cell sag begins to play a part. The VW button had a simple(lol) switch as well, and low profile.

For 24mm small tubes, I always thought the Bastia and Quake clones were excellent! The side-fire allows the mod to be shorter than the older, bottom fire button style, as well as having less parts to break/clean/steal voltage.

It seems they are gone too? Wow, we really don't have much to choose from in the "small,22mm" mech tube arena.

Shame. Makes me want to ream my ass and climb the wall! lol, sorry.

The 3 copper SMPLs in test now have all the screws and magnets.
But I have others with circlips, I think they have springs.

With a simple Ohm-Meter I had on all 3 about 0.5 Ohms
between the pressed switch head and the tube.
(battery IN and a dummy atty).
But these simple Ohm-Meters are not very exact.

I still think, the problem are these notches/teeths,
they should switch the current mainly.

And I still think what happens on battery plus with these black dots,
will similar happen on a brass to brass switch,
thats perhaps the reason why they have silver or gold plated switches.

First I will try now with vinegar.
Now with 0.33 Ohms the mods stay cold,
I will coil them to 0.20 Ohms to see which part of the mod gets hot.
