I had the same complaint about the evod
batteries with the flat button. A few things I did. At the dollar store you can get a small
pack of nail gems. I found real little gel like ones thatwere a very pale pink, almost clear. They didn't
show but they added just enough extra height to help find the button by feel and added a bit of softness. Each only stayed on for a few days but there were about 20 in the pack. I also just used elmers glue and put a bit on, let it dry, a bit more, etc. to build up the button. Just be careful not to get any in the area where the button goes down.
