Together with the 60W+Fodi I got from the VE Sunway chip chip opening sales as a backup mod.

Funny I actually got the 'Cado *because* of the Fodi lol: Was using it as a dripper (and still is, note empty tank) and it gave me so much flavour even while semi-lunging I was immediately sold to the entire GennyReborn idea.

How much is avocado - thinking of getting one

Check the insulator that is sandwiched in between the 510 pin and the top 510 screw. It might be loose. Heck the entire top 510 screw might be loose.

Otherwise the post screws. But you said you already checked those.

Using the smaller brother, but yeah close enough. Nope not having this problem at all, though I'm not running Claps myself (staying on straight spaced SS). What mod are you running?

On the other hand, I did just go though a similar issue (wild resistance jumps and subsequent TC issues) with twisted SS on my VeloV2 (after hours of fuss free vaping). Turns out my coils were so huge that one of them were touching the top cap everrrrr so slightly lol. A bit of coil adjustment fixed that up quick.

As a Cado is pretty much a Velo on a tank, any chance of something similar happening?

I don't have those, but I might just be lucky. The insulator is *probably* the problem as even seated prefect some of them just wasn't made that well (ehem GV).

Also, authentic? Might seem to be a pretty dumb question but there has been cases of clone 24 Cados being sold off as auths over here (even with auth sticker and all). Key point being the fill port will *not* have any silicone in them on clones.

Check the FastTech product forum for the Cado. In most TC/resistance jumping issues, they usually have issues with uneven/damaged insulators (some even straight out of the box). They also have posted some fixes using small orings.

Which is a crying shame as when it works well, it's a pretty awesome tank. But yeah, the Cado does eat juice for sure. Not sure if it eats more than the old TFV4 coils though lol.

That just an extrapolation on my part. GV might have improved the 24, but there will always be lemons... unfortunately.

Why not go back to the shop for an exchange? Maybe a new unit would work better.

I like to switch juice after each tank. Was trying to remove the reservoir of the Avocado just now for a clean up and re-wick. Found out that the positive pin connected to the positive post, have to be slightly careful not to accidentally moved the positive post or else the coil will be ruined. It's that a con? Well at least yes to me, personally. Or is there other way to clean the tank?
