The service works ok, hence the 2 stars. But they automatically put you on annual autopay, then refuse any refund if you want to cancel sooner. They claim to have sent an email to me notifying me of a renewal last April, but I just verified that I never received any such email. So they have charged me their full, expensive annual fee without notifying me, and now less than 6 months after the renewal date, they will not issue even a partial refund for the remaining time. I don't even use the service, and I just want to cancel... but I have to continue paying for ~7 more months. Also, they have no way of cancelling or changing autopay settings on their site; you have to call them and wait on hold to talk to somebody in order to make any billing changes. When I asked to speak to a supervisor, I was given the runaround and then put on hold for 20-30 minutes before I finally got a supervisor on the phone who was not willing to help. Very archaic and short-sighted approach to customer care if you ask me.
Chrome remote desktop is free, easier to use, and doesn't use 'gotcha' billing tactics.
