I got a dead Uwell Crown. You can have it if you are willing to come to Setapak.

Free for the o-ring. PMed you the number.

Not to be all anal, but I don't think the Serp is an RDTA really, it's more a "straight" RTA. Both the 'Cado24 and the SoloFodi is pretty much RDTAs though.

From your list seems like you plan to run single coils (Cado = adapter, FodiF2 = single coil by design)?

Which is a shame as if you can do duals I'd say the iJoy Limitless is a pretty interesting RDTA. It's like the 'Cado and Theorem all rolled into one.

Also the Aromanizer, especially the Supreme one.

Vail isn't Pink a more hazelnuttish cream kinda? At least the Pink I know of is ler (the Dwap one).

The Corolla has a fill hole...but it's really tiny. Have you tried filling from a bottle that has a steel dispensing tip of the proper gauge? Maybe some vape shop or pharmacy near u carries such bottles...or u can order online from lelong, altsmo or fasttech.

single coil? have you look into obs ace?

I use MNKE for my stout, normal usage (15-20 watt) can last me whole day. But it didn't do great on high watt. Now am switching to AWT, a bit expensive but more better than those MNKE.

Sometimes i get the notification,  when the battery left half, and firing at high wattage. That normal for low amp battery.

Yup the AWT is yellow one, around 45-50 each. They also have a red one, but didn't try it yet.

If firing at 16 watt and go low batt after 5/6 puff maybe it's battery problem, but u can try other battery first to confirm. Try 18650 and see what happen.
