A robot that my son really wanted for Christmas was broken when taking it out of the box Christmas day (motor on foot did not work so it could only walk in circles ). This is actually the second one of the same robot I got him since the first one broke from him playing to rough with it and he has been asking for a new one ever since. I couldn’t return because I lost the receipt, so I took it apart found the loose wire resoldered it put a shrink tube around it and now it works just like new . He is so excited !!
