Thanks a lot!
I am the developer, manufacturer, and the seller from Beijing,China
I upgraded the plug, this is reason why you find scratch on the body.
I drill the holes by hand held driller.
Wireless Remote Controller, the model of TIGER is out of production.
I can not find plastic case for the display set. Minimum order is 1000 pieces.
If your buy 100 pieces, I can place the order of 1000 pieces of case.
I need a partner in American Market.
A small, really small Li-metal battery can power the set for 10+ hours.
I prefer battery than AC/DC adapter for safety reason and easy handling
Basic model WOLF and WIFI model TIGER are available.
