V2 Vsavi Classic Blank Cartridges

I have been using these blanks for a year. In my experience they last far longer than people claim if you keep them topped up. I don't let mine run dry and have one in my car on one of the USB PSU's I use on every journey and have done for a couple of months - when do they wear out! really really good product. Smoke for 30 or 40 puffs and then top up. Simples. And I prefer the taste to the refillable clear ones.

It gets worse with each purchase. I've been a loyal customer for years. These blank cartridges used to be great, but it looks like they make them cheaper and cheaper??!!!???
If one of the 5 cartridges provided in a pack works you're lucky!!!!! They don't absorb the liquid, and it feels like a burn flavour on your throat regardless how carefully you refill it, or if your battery is new.
Response From Team V2: Please could you contact us as soon as possible as we would like to resolve this with you. The design has not changed but we have noticed that, on a very few, the removable bung for filling the cartridge is sometimes out of the cartridge itself. We have reported this. You should not be experiencing a burnt flavour unless the cartridge is spent and needs to be refilled. We would like to get to the bottom of this as soon as possible.

I bought some blanks and the first one only lasted me 4 days on holiday before i was unable to vape anymore after topping it up with E Liquid. My second blank cartridge I'm still unsure about as it seems to get to "burn" flavour quite quickly but has lasted me over a week so far. The short life span of the first blank may be down to the E Liquid which I'm ordering off another site, it may also be because I'm new to this. So I'm reviewing but i'm still unsure!

Got these as the reviews on the clear ones were less than consistent with regard to quality. Very easy to refill and last as long as the prefilled cartridges. I find they last longer than 5 refills and do not leak at all. A good money saver on the 5 pack, as this lasts me a month.

Very easy to fill. Takes a few mins to soak up liquid. Great to try differant flavours . The only thing i could suggest is different colour stoppers to show different flavours. Will get more . Oh and they last ages .
