Congrats! That was my very first device and a great one that helped me enter the vaping world. 25W of power, 2ml capacity, 1500mAh battery - perfect for a beginner vaper. If you stumble upon some, male sure you get some ProC BF coils @0.6 ohms, they're a bit more durable than the standard ones. If you want to experience DTL (direct-to-lung) inhaling, find the Cubis 0.5ohm coils.
For standard coils, make sure you prime them with two to three drops of liquid directly into the center, for 0.5ohm coils, soak the cotton inside well - in either caee, leave the new coils in a filled up tank for about 10 minutes to soak before first use to avoid a burning taste and having to immediately replace them with new ones.
