I bought a new Yoga 720 and it immediately made the loudest sounds when working. It was embarrassing to use this laptop because of how loud it was. Touchscreen stops working randomly and customer service is trash. I sent my laptop in to get repaired only for it to take almost 3 months to get back. This is ridiculous. Not to mention that they refused to provide me a loaner device. Now that my warranty has expired, my touchscreen continues to turn off with no help. I call customer service to be placed on hold for 30+ min. Don't waste your money on these.
