I have the vivi nova style tank. How long are your heads lasting? Also, how well do they do with dark juices? Ive been solely a carto tank guy for a loooong time and dark juices just dont work for me. The carto tastes burnt within a day or two. Hoping to have better luck with these heads. Im missing out on some amazing tasting juices that burn out my cartos way too quick.
Thanks.
Thanks.
