Since it's on sale for the same as TTP, for 25 bucks, I decided to try it.
Observations before even using it:
-Won't install on a partition so I can use the rest of a USB stick for something else. Have a 32GB one here, made a 10GB partition for it, but it won't see partitions, only devices, so I'm letting it chew up all 32GB to test it. This is one sign that it might not be meant for techs, who might want another bootable partition with a different OS and set of tools on the same drive.
-If I try to add Disk Warrior to the app list, it crashes. :^)
-The web page is pretty sparse on factual info, so it might be helpful to know that, once installed, TTP app is in its own folder separately for use, not only as part of Protogo. IOW, you get TTP 7 and the extra money (normally) for PTG is for the convenience of making a diagnostic disk.
