How accurate are budget torque wrenches really?

Mainstream click-type wrenches in the $40–$70 range typically advertise ±4% accuracy, and YouTube accuracy tests cited by community reviewers generally back that up in the middle 20–80% of the range. Accuracy degrades near the top and bottom of the scale, so reviewers across the tool subreddits recommend buying a wrench whose mid-range matches your most-used torque values.
