The nightmare started when our Mclaren P1 remote controller broke. Several folks tried to fix it, including an electrical engineer, but it was past being repairable. My therapy dog rides this car for military troop deployment briefings, hospital pediatric/ cancer wards, military clinics, USO, Red Cross, etc. To find the part, I googled and called every ride on car companies and parts suppliers that was listed. Those companies whom had the part Refused to sell us the part because I didn’t purchase it car from them. I found one company that would in Whales (Europe) but the don’t deliver to the US. Finally I happened to call Bog Toys Direct and the sent me the link to Toypartsnaccessories! They were Awesome. Not only did they have the controller, they shipped and it arrived lightening fast!! Both of these companies were Professional and Friendly, with Excellent Customer Service and Delivery! The best bar none! Highly Recommend !!
