I just purchased a cleito 120 today and the tank is certified. I primed it properly but i noticed the ohms were reading wrong. I hit the fire button and every time the ohms change. Never seen this before. The tank got really hot and took a long time to cool. I changed the coil thinking it may have been a bad batch coil. Nope same thing. I switched from my asmodus minikin 2 to my good old rx200 to see if it was the mod. It was not. The rx200 read attomizer short. I then used a smok tfv8 big baby beast tank to verify the mods were working properly. And they are. Cleito coil is the .16 ohm. And the smok was the v8-t6 reading .2 ohms. I emailed aspire about it but i figure I would see what the forum could help me. Thank you for your time.
