Button models like the PockeX use the standard five quick clicks to power on and off. The Gotek kits are draw-activated with no button at all: inhale and they fire, then sleep on their own between puffs.
Gotek pods fill through a side port: pull the pod, lift the bung, fill to the line. The PockeX fills from the top by unscrewing the mouthpiece section. Either way, give a brand-new coil or pod five minutes standing after the first fill so the cotton saturates fully.
The stock 0.6 ohm coil sits between MTL and sub-ohm, so it handles 50/50 liquids and thinner shortfills well. Keep nicotine at 12mg or below with that coil; a 20mg salt through a 0.6 ohm coil hits harder than most people want.
Charge it on a mains plug, reseat the pod or coil, and clean the contacts. On draw-activated Gotek kits a flooded airflow sensor can pause firing; leave the device upright for a few minutes and take gentler puffs. Persistent problems with a fresh coil are warranty territory, so get in touch.
They are one of the safest choices there is. The Gotek X costs less than a takeaway, runs on cheap pods, and does nothing complicated; the PockeX has been recommended to first-time vapers for years for the same reason. Pair either with a nic salt and you have a complete switch-from-smoking setup for around £12.
