Hi all I have been using the istick power 80 since giving up smoking 2 years ago and have two of the same devices. I also bought a obs cube x about 6 months ago which I really liked other than having to charge and change batteries. I dropped and broke that one couple weeks ago so don’t want to replace. One of my istick is being very temperamental at the moment so am looking for another device. Can anyone recommend any that’s like the equivalent of the istick (internal battery) and a good battery life that they find is a good vape. I vape at 40w. Thanks in advance.
