    Finally a set of batteries that last ALL DAY without having to have a charging cable next to you. Yes expensive but worth every dollar.

    These batteries are great!
    I use a Geekvape Blade with a Cleito 120. The iJoy 5-leg 20700 batteries I was using lasted less than a day. I got 2 solid days of use out of a pair of these. Long charge time, but that's to be expected out of such high capacity batteries. The iJoys are short-term backups now. Will be ordering more.
