Greatest invention ever. Every single one of my kids toys requires these screwdriver especially if I have to put batteries in it. Now i have my very own set in its own case that I keep right by chair for the next time they need to get a battery replacement. All reality though I use these screw drivers more than regular ones any more. Like fix glasses , rescrew that screw on the side of a pot the other day. Made of great quallity.https://www.amazon.com/gp/product/B0768DFCR8/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1 #RankBoosterReview,#Sponsored, #Dstore
