I am trying to find a cheap mech mod that uses the 18500 battery, simply because I already have two of them. I have a ehpro sentinel actually two now, and the threads on them will no hold the tank. Madvapes already replaced it for me once but the second one is now useless as well. Would be nice if I could just buy a new top, but nope can't do it. I also have a k-103 which is ok but the button is too hard to press with my tiny arthritic hands. Any ideas. I really love the sentinel, but can't keep asking for replacements and sure aren't going to buy another one.
