Not a replacement for ARD
It’s ok if you just want to connect back to your home computer or help your aunt Myrtle send an email, but its not ready for small or medium business IMHO. It regularly loses settings. It’s ability to configure a router is questionable. Documentation is sparse, in particular anything that you might do to help it configure a modem. If you write to them asking for information, you’re ignored. My version just stopped loading screem images after 3 for some reason. I can still connect, but only by clicking on the name of the computer in the right side list. I just got the newest update on 5.4.14 but none of my issues are fixed, though it does seem faster.
