I've been carrying egos in my front pocket for almost 3 months now with no issues. I now carry that and my Natural. I can see that when you allow the battery to lie side ways in your pocket and you sit down it may be adding to much pressure to the connection and flexing/breaking. I carry mine upright against the leg seam, or in my "5th pocket. I can fit a ego twist with a slim xl carto tank in my 5th pocket no problem. No issues with either mode of carrying. Just be mindful of where your mod is.
