Really like the vape and my mouthpiece was ready to be replaced after 4 months of frequent use. So pretty decent life for the mouthpiece. However, once it gets to the end of its life and if it gets too hot the mouthpiece begins to burn silicon or whatever material is around the filter. So I would like to see some updates made to the mouthpiece interior so I know I’m not hurting my lungs. Other than that product feedback it’s an inexpensive and good replacement for $18.
