The Triton II battery works well but there is one problem with the system. Namely, the glass tube on the tank will often shatter if you drop the cigarette.
Triton ii is my favorite
Love it and paired with Tribeca, a most enjoyable non-smoking experience.
I alternate between 2 batteries a day.The life of the batteries are about 4 months.Is this the normal life span of the batteries?As for the performance of the daily use,I'm satisfied.
