At the end of June, I bit the bullet and bought the pricey Hot Lights Damager Police model for my 5 year old.  He was thrilled with them, and when they worked they looked great.  Unfortunately, 4 days later the lights on the strap were out.  We went back to the store for an exchange and got a new pair.  Four days later....you guessed it - the lights on BOTH straps went out.  I let him continue to wear them for another week, as the Skechers store is over thirty minutes from my home, and at this point only the lights on one toe are working!  We're going back today for ANOTHER exchange, and I'll be sure to get a different model this time.  It's a real shame too, because he wanted this particular pair - his dad's a police officer.
