As soon as I saw the nicad batteries that came with it I knew at the very least I could turn the body of the tank into a charger using the USB charger they provide. The tank also has quite a few colored LEDs in it, red, green and clear.

the postage to China thing is a scam they've been using for quite some time. Creality tried that on me when I wanted to return the resin printer I got from them that had no viable software. When I called PayPal I got a young man named Daniel and I basically told him that I have been scammed by the Chinese and he personally has seen that before and doesn't like it at all so he went out of his way to hook me up. He issued my refund right on the spot. A friend of mine in the business tells me that PayPal probably won't take action, and if they do, by the time they get around to it the scammers will have abandoned the account and moved on to something else. There is, however, one philosophy that we might apply to scammers like this ... KILL 'EM ALL!! Yeah, I know, wishful thinking, but I still get a kick out of it.
