I found that an eyeglass screwdriver, the kind you get in the little cheap kit at the grocery store, worked better. It's flat, so it doesn't tend to warp or break the little plastic caps nearly as much. And unlike an icepick, it's not sharp so my clumsy fingers didn't get poked.
YES! Thank you! That is what I ended up using, its been a WHILE since I messed with cig-a-likes, but you jogged my memory!
