The KDS EGO Battery
These are made by Shenzhen Kangshengda Technology Co. the battery isn't built like a normal EGO the center contact is not glued in place. It only works with some of your EGO chargers it isn't reverse polarity like a VGO from Huizhou Everybody Health Technology Manufactory it is just crappy.
The 580 Cartomizer
I have Apoloe and Rocket 580s those are well made what this is, well saying that is it not built well is like saying that my food is cold. This thing was built by blind people using their feet....
The plastic tube is low grade plastic the bottom of the tube is not glued in place and will dump juice on you if you pull the dust cover off while attached to the EGO. You have to turn the dust cover against the the threads then pull from the top.
Vendors take a pass on Shenzhen Kangshengda Technology Co. for now.
