This is first impressions, but based on 3 days use.
I bought a pack of LR atties with the ego c.
I vape mostly thick sweet flavours which I have found I need a booster with on the Tornado Tank
(or 2.4-2.6 clearo's rather than 2.6-2.8 )
Vaping marshmallow (DV)
Normal atty on ego c= very little taste
Normal atty on ego c + booster at 12 0'clock = nice taste, any higher = burnt taste
LR atty on ego c = nice taste
Other flavours follow the same pattern always the LR giving the same or slightly less flavour than with the booster
No clue yet about life, but real happy with performance and I WILL be using the LR as standard (the booster is great but makes the assembly pretty big to carry around)
