Overall Verdict: 4.2/5
One of the better manuals in the sub-$500 CNC category. It won’t win design awards, but it will get you cutting wood safely.

As someone who has assembled half a dozen Chinese CNC routers (Genmitsu, FoxAlien, Sainsmart), I judge a machine by its manual first. The TGC BC-901H manual is a pleasant surprise. It’s not perfect, but it avoids the usual pitfalls of Engrish, missing steps, and dangerous electrical guesswork.
