Are the inexpensive Amazon brands like Huepar, Cigman, and Takamine actually accurate?

r/Tools and r/electricians threads repeatedly report that mid-priced Huepar and Takamine units measure as accurately as $500–$700 name-brand lasers for typical residential work, though build quality, drop resistance, and warranty support are weaker. Specialist communities are more skeptical of the lowest-priced no-name units, citing calibration drift and short service life.
