I work outside and today is the first semi warm day around here since I quit analogs. I'm vaping in the sun with a black itaste VV box loaded with a ViVi tank with a black metal sleeve. I noticed as my PV started to warm up I seemed to be getting a more flavorful vape. When I inquired as to why this may be I discovered the juice in my tank to be more viscous than I've previously noticed. I'm assuming this leads to better wicking and vaping. Anybody else notice this before? Should I have concerns about overheating?
