Teenager Who Lost Both Hands as a Child Applies Makeup Using Bionic Arm

The 'hero arms' cost approximately £10,000 per arm to purchase, although Tilly has been given multiple different sets to trial due to her role as an ambassador for the company. Tilly said she loves the simple things about the arms - including being able to hold two items at once. She said: "I really love how I can now hold two things at once. "It sounds really simple and it is probably what a lot of people take for granted but to me, to be able to hold a book in one hand and a pen in another while I’m studying is great. "I also love how cool they look, they’re lots of fun and I’m proud to wear them.”
