I recently bought a Sunbox E7 off the ECF classifieds. It shorted out ruining the chip and charger after about 39 min. of use. Now I'm in the process of rebuilding it. I'm cleaning everything since I found juice in the chip compartment and I'm having a problem removing the drip cup. It's the UFO type (low profile 22mm).If anyone has installed a drip cup on a E7 I really need some help.
