Query: It's a bust

This is the third snap circuit setup I've gotten for my boy, and the prior experience has been first rate. With this one, the plastic controller battery housing requires opening a door affixed by a philips head screw, which stripped in the attempt to install the first battery. So I'm stuck. For $[...] they should be able to find a screw that's made of something other than aluminum and installed by someone other than an arm wrestling champion. This gets an F each for design, assembly and materials.
