I've been using these for a few years, now I think they're end of line hence very good price.
I bought 2 at that price, they usually last for 1 year or more. If you buy them you'll also need a supply of the cartridges, because they are probably also discontinued
I bought this as I had the mod with another type of tank for going out on walks, but the tank leaked. This one is great. All the flavour youād expect from Uwell, but none of the soggy pocket nastiness, even with a bubble glass fitted.
