At US$20, this sits well below the US$70 25th percentile and miles under the US$134 median for recent used comparables, so it reads as a strong bargain. For a compact class-D integrated amp, that is the kind of price that makes sense as a casual desktop, workshop, or secondary-system grab.
The appeal here is straightforward: these little SMSL units are popular because they’re small, efficient, and usually deliver clean, punchy sound for easy-to-drive speakers. At this level, the upside is hard to argue with if it powers on cleanly and the knobs, inputs, and speaker terminals are all healthy; a complete, tidy unit at US$20 is very easy to recommend.
