You get what you pay for. Full guarantee and there is electricity! I just wanted to keep buying harbor charters but now I'm glad I got this one! If you're throwing a frame or thick metal I recommend using a side handle because if the bits bite into the metal this thing will kick back a little. BUY No worries here. I always use good air oil every day. I haven't lost the rhythm yet and am busy modifying the trucks and drilling the frame all the time.
