It is a three piece e cig, so it is not a KR 808D1 If you are getting good vapor but not throat hit, then the liquid is probably the problem. Go to HIGH VOLTAGE Liquid 12Mg 30ml Plastic Dropper Bottles and order some high voltage in the flavor of your choice. Rasberry Frapuccino and Pralines and cream are excellent.
OR try whiskey for great throat hit

Get the highest nicotine level. I use 24 mg, but many need 36 mg. The lower the nic, the lower the throat hit IMO
