The really good news after continued use of the Evo is that imho they get better over time. The atomisers become less "aggressive" and noisy whilst still producing good vapour. I have also become accustomed to the length and weight of the Evo in comparison to the original Intellicig. Topping up the Evo cartridges is really simple when still in the mouthpiece if you tilt the mouthpiece with the air gap uppermost. The liquid settles into the cart fibre easily. Also leaving the cart stood on end for a few minutes ensures better absorption of the liquid. I haven't tried the new type of Evo cartridge yet so cannot comment on those.
It's very portable, very reliable and has great battery life. I now use the Evo in preference to the Original when out and about, though I still use the Originals at home. To my mind it represents great value for money. Interestingly I find that I spend very little time thinking about the Evo now - I just get on and use it. I think this is because it has few quirks to trouble my elderly peabrain
. In short it's a valuable addition to any vaper's armoury, and on reliability alone I have to rate it very highly indeed!
