Hello all!   My T3 clearo is getting really hot to the touch.  The (factory made) coil is about 2 weeks old, has been washed and dry-burned twice, and still produces decent vapor.  I usually run the 2.1 ohm at around 4 volts.  Should I be concerned that the clearo--especially at the bottom gets pretty hot?  Is it because the coils are getting ready to pop?
