It is a project radio, and that is how I went into the purchase. Think more or less an assembled kit, and you get to "fix" it to some usable state.
Still waiting on mine, but I did get shipping info recently, so maybe it will arrive in a couple or so weeks.
I did a quick skim of a Si473x community awhile back. Somebody was working on software. Spotted info about cleaning up and stabilizing a similar (or same?) design with filtering caps.
Assuming mine even works at a basic level, I intend to add more power filtering, basic ESD protection, and perhaps some type of input matching.
All that said.... yeah, definitely instead buy a known decent radio if actually wanting something usable out of the box. :)
