One of my faves, have had many, none defective! Flavour is great, definitely lasts for me & you clearly see how much you have left, no more guessing how much % of juice you have left, easier than judging by a bar or light on the screen. Will keep buying until they aren't available.
☆☆☆☆☆Customer Service is so great when I've had any issue or question. A Real human answered the phone, no waiting on hold forever & very helpful!
