What caught my attention about the Crystal Pro Switch 30000 Box of 5 was its dual-flavour system and smart display. I ordered it from Vape Zone Wholesale at 3 PM and received my parcel the following day before 3 PM. Each box contains five kits, with every device featuring an 850mAh rechargeable battery, USB Type-C charging, a 0.8Ω twin mesh coil, a 2ml pod and two 10ml e-liquid tanks. The display shows useful information about battery level, puff count and e-liquid status, while the twist-style mouthpiece allows switching between two flavours. The advertised capacity is up to 30,000 puffs per device. Product link: https://vapezonewholesale.co.uk/products/crystal-pro-switch-30000-box-of-5
