I have scrolled through earlier reviews and agree entirely that Vype's customer care is first class - efficient and courteous. I moved from the e-Pen to Pebble and think it's a good product. Its shape is discrete and its function fine. The battery life is not long [albeit charging is pretty swift] and I'd recommend having two devices. The equipment has failed me twice for no apparent reason but each time a replacement has been quickly forthcoming - back to my praise for the great back-up. I would recommend that you stop calling the devices e-cigarettes as they get too easily included with smoking restrictions. Vaping etiquette is important but should be distanced from tobacco smoking.
