Review on 📏 ANNMETER AN-700B Digital Multimeter Pen Type with LED Light Indication Meter - AC Volt 1000V Reader, 500H Frequency Tester by Polo Bradley

Good design. Comfortable case, feels good in the hand. But when my device arrived it had a dead battery and the cron kept disconnecting from the power cords causing the device to crash and shut down. The battery had to be refilled constantly. It is also very difficult to change the battery. Small deep holes with tiny fragile screws. You need a special screwdriver and have to unscrew them very carefully. Overall the block is poorly built. I wouldn't rely on it professionally. Possibly for home use. But I would invest a little more money in something more reliable.
