New Multi Function Remote Control Robot White and Black LED Lights Woboto USB powered robotics

This is simple robot toy with forward motion and can turn. Simple to operate and fun for small kids. I bought one of these at a local store three years ago for my 3 year old. Now I have another three year old and wanted a second because these robots can be controlled separate and both can play at the same time. The biggest issue with these is forgetting to shut the units off and running the batteries down. I have been using easier to find 357 button batteries, each robot and controller needs five batteries. These robots are hard to find and I suspect may be a discontinued product. Could be a collectable if the kids don't destroy them.
