I have 4 or 5 of the 'Free' Harbor Freight metes. Verified them against a
Fluke meter that was verified against some very high accurate lab gear. The HF

My HF meters are all pretty accurate, as long as the battery is fresh. My yellow ones do not have any low-battery indicator, so the only hint is when the readings do not make any sense (which may be a challenge for an inexperienced user).
