Anydesk v Teamviewer

I need a remote solution for connecting to multiple remote machines (customer PC's in multiple locations)

I currently use TV version 10. So it now needs replacing or updating.

I have seen a product anydesk which seems to do the same functions only it's a lot cheaper.

Is there any disadvantage to using anydesk over teamviewer?

From what I can see you need to buy TV each year to keep it up to date
whereas anydesk you get the new updates with any additional cost.
