To all my friends here, a very MERRY CHRISTMAS and Happy New Year 2019. And Happy any other holidays you celebrate (Hanukkah is complete, so in that case I hope it WAS good).
We just switched to AnyDesk and we are very happy with it. We're using the free version now but will likely pay for it soon.

Clients don't even have to install it. Just run the download whenever you need to get in.
