They renamed to Obico. As for how well it works: the answer is pretty well. When a print starts failing, it fails quite dramatically typically. You just want to know if the print is going to waste a bunch of filament or potentially embed itself into your hotend. Figuring out if you start spraying filament everywhere is pretty easy to spot. This isn't intended to spot subtle layer shifts or something, it's more about fatal errors that left unchecked will just throw away filament or (in a worst case) ruin a printer.
