Review on Tepsmigo 2-Pack Tactical Vest Kit For Kids Boys Girls 5+ With 100 Refill Darts, 2 Reload Clips, Face Tube Masks, Hand Wrist Bands & Protective Glasses by Aaron Hawk

The grenades SAY they take two 1.5 v batteries BUT there are NO contacts for them! Also, there are NO wires inside of them & NO electrical components of ANY sort! Why buy batteries if they can't do anything?My autistic 9 year old keeps asking me to put batteries in them so he can make them work, I can't get him to understand that THESE grenades CAN'T possibly work even WITH batteries. Did the company just FORGET to put the battery contacts & electrical 'stuff' in BOTH of them or what am I missing? What good would batteries do?
