Bit late in jumping in, but I've had the tarot nano kit for about 6 days. Late birthday present. The mod itself looks lovely, got the rainbow abstract design;sits in the hand well, small and nice weight/balance. Buttons nice and easy to use.
Downsides - Battery could have done with being a bit more powerful, it drains quite quickly and also takes a while to fully charge.
With reference to the veco tank and coils supplied with the kit. Mine had the standard EUC universal coil preinstalled and a spare 0.5 EUC. I actually emailed Vaporesso yesterday out of frustration as was having similar issues to everyone else with flavour, was getting some, but also a weird aftertaste. I started out dropping some liquid on the coil, topped up the tank and let it sit for around 10 minutes before vaping.
Cant remember what the recommended wattage came up at, something like 33.4? Anyway, started a lot lower as had read it was best to slowly increase wattage until you get the desired sweet spot. It just wasn't happening. Cloud/vapour production brilliant, taste meh. I ended up getting low on juice and got that dreaded burned taste/hit, panicked but persevered...refilled the tank and gradually increased wattage. Using Naked 100 Hawaiin Pog 70/30 Finally, I'm getting a fruity flavour with a smooth creamy vapour. Six days of messing about and a lot of juice wasted I'm almost there with the sweet spot for me at 41.2 watts. I still think strength of flavour is slightly lacking, but it's enjoyable. Maybe just takes time for these coils to 'bed in' Shouldn't be taking that long though! Or maybe it's the juice/liquid I'm using?
