The a2 is decent performing pod ideal pod kit full of flavour from its rather loose drawn 0.9 ohm pods, what makes this kit absolutely ideal it's completely lightweight it's brilliant for a first-time transition from smoking, completely compatible with 50/50 VG PG nicotine liquids whether being freebase or salt juices, with juice window helping you to gauge how much juice you have before you have to refill the pod which is a huge upgrade from its previous model, so why haven't I given it before five star? For me personally the battery life he's a little bit lower then I hope.. at only 520mah providing you dont use constantly you can get away a full day with charging once, aswel as having a USB-C port it will charge fully in bit over half an hour, most people have access to plug or portable power bank which are dirt cheap aswel these days...
