Clouds? Fine. Taste & scent? A must! Any issues breathing... I pay attention too as it may be a VG/PG or some additive my body does not agree with.
Have not had any issues with gunking up the coils I'm using at the wattage I'm using. I usually stay below the wattage range recommended on the coils, and they last much longer.
I'm lucky to live in Chicago, with family 35 SW miles of me. Lots of vape shops within 30 miles! I've been vaping for around a month now and dove in head first. I try and visit at least 4 new vape shops a week within 30 miles of home and probably have around another 6 months or so before I cover them all. I started by visiting a few vape sites, plus Reddit, to see what everyone was vaping, and ordered some liquids online.
Whenever I go in to the shops, I ask them what their top two vaping liquids are and often buy them, most of the time without even trying them out. I then may/may not try other liquids. This gives me a clue as to what is being sold out there and keeps my mind open to new vape stores, vape customers, and what is being sold. If they burn me and sell me something really bad, I may not go back. I certainly will be going back to places that b/c my everyday goto.
I bought a few tanks so that I did not have to rotate one tank so often, and am able to enjoy several flavors throughout the day.
Within that one month, btw online and retail store purchases my collection includes:
2 - vape liquids I am not fond of that I bought online.
26 - different 30ml liquids
2 - 125ml flasks of liquids I liked
1- SIGELEI 75W mod
2 - Aspire, Atlantis II tanks
1 - Aspire, Triton tank
Quite a few boxes of coils in all different ranges, but mostly 0.3ohm, as I have found them to vape the cleanest. Coils rarely have to be replaced when vaping at 45 to 50w on 0.3ohm coils with my setup. Cannot say the same for 0.5ohm coils.
