Just purchased an Arymi one pro. Havn't tried it out yet. It was only 35 quid and looks really nice in silver. It's a 75watt single 18650 mod and manufactured by kangertech. Will be poping a battery in it later to try it out. Came with a 90 day guarantee from vaporised Derby in the UK. Anybody else got one of these and if so how did it hold up. ? vape on.
