Has anyone tried using Taopatch?

I saw this ad for a product called Taopatch and it supposed to improve balance & overall wellbeing. The least expensive product they offer is $299 for 3 patches that last 30 months. Has anyone tried this product or know someone who has? What was/is your/their experience?
Sounds too good to be true, so it probably isn’t. I understand how people can be taken when they are so desperate to find something that can possibly improve their quality of life.
Any info is greatly appreciated. Thanks!
