Hi,I don't like the 20 watt because it has a delay when You press the fire button,it takes at least a full second to respond...I have looked everywhere to find out if its just Mine,or if all the 20 watters do this...If You can put up with that little fault it is a great mod for the money IMHO....ZApologies for the off topic question, but OP, how do you like your Kamry 20 watt mod? Thinking about picking one of for an older friend of mine who wants something a bit better then his eGo setup. Thanks!
