Just bought one of these to replace my battered Coolfire 4 plus and am having problems. I'm a simple MTL vaper and use a nautilus aspire tank with 1.6ohm coils. This tank works great on my coolfire 4 plus but when i put it on the coolfire ultra and set it to vape in Watts it gets to resistance of the coil wrong and reads it as 2.09 ohms. This has resulted in coils burning out in less than a day with a very unpleasant and bitter taste.
I contacted the seller and he tells me that i should be using the tank that was supplied with the mod but this isn't any good for MTL vaping. I believe the coolfire ultra should work correctly with my aspire tank and get the resistance of the coil correct. I believe the Coolfire Ultra is faulty and should be able to read the resistance of the coil i'm using correctly. Any thoughts? Thanks, Mike.
