I'm using Coco Nara and they are absolutely a nightmare to light for me because I have an electric stove, not the once with the circle thingies but the flat ones plus I don't have a torch lighter. However, I just bought a portable electric single stove especially for coals from nazarhookah. You should really get one since they are on special for only 9.99. The ones at walmart are almost 30 bucks.
I'm sorry it's actually 14.95, but I bought one yesterday for 9.99 so I lucked out there since the special ended, however it's still a great buy and cheap.
