The CAT rating is a safety specification, not a quality grade · review
A true-RMS auto-ranging meter that lights the correct input socket in green for the function selected — the one design idea in this hub aimed squarely at the mistake that damages meters.
What the figures leave us with The lit jacks are the best idea in this hub. The missing category rating is a gap most of this hub shares — though the coczow and the KAIWEETS KM100 both print one.
A meter designed around the mistake people actually make.
Auto-ranging true-RMS measurement of AC and DC voltage, AC and DC current and more. Depending on the function selected, the correct input jacks light up green — stated as an aid for beginners and students. A large 6000-count display with backlight, a dual display and a bar graph. A non-contact voltage detection and live function with sound and light alarm.
Every multimeter has separate sockets for voltage and for current, and current is measured with the meter in series — effectively a piece of wire. Leave the lead in the current socket, turn the dial to volts, and touch a live supply, and you have connected that near-short across it. It is the single most common way a meter is destroyed and a fuse, or a person, is put at risk.
Lighting the right sockets for the selected function turns an invisible error into a visible one. No other meter in this hub does anything about it.
A contactless detector built into the meter is convenient and it is not a proof of isolation. Its silence depends on insulation thickness, screening and how the tool is held. It belongs at the start of a check, never at the end.

The commonest destructive error with a multimeter is leaving the red lead in the current jack and then measuring voltage — which puts a near short circuit across the supply. KAIWEETS states the correct jacks light green for the selected function, which makes the mistake visible before it is made.
No. A contactless detector says "there is probably voltage here", never "this is safe". Confirm anything you intend to work on with a two-pole tester that loads the circuit, and follow the manufacturer instructions for both tools.

Same category, nearby prices, between measuring instruments. What remains is the specifications every one publishes — half empty, a column is no use.

True RMS · 6000 counts · 600 V · temperature, capacitance and frequency
A true-RMS meter with 6000-count resolution and a wide function list — voltage, current, resistance, temperature, diode, continuity, capacitance and frequency — with probe caps included.
Best for: Household and light installation work where waveforms are not clean and the reading has to be right.
19 RANGES, the only range count published on this shelf · 10 MΩ input impedance, stated for automotive computer circuits · automatic POLARITY sensing · automatic zero on volts, amps and battery tests · battery tests at 1.5, 9 and 12 V · the ONLY meter on this shelf sold WITHOUT its battery · NO measurement category
An automotive meter built around the one specification car electronics actually need — a 10 MΩ input impedance.
Best for: Car and bench electrical diagnosis, where the circuits are 12 V and the sensors must not be loaded by the meter
≈ $11
AC/DC voltage · DC current · resistance · diode · double ceramic fuse
A compact meter whose distinguishing specification is its protection: a double ceramic fuse stated as flame-retardant, plus a silicone sleeve, at fourteen euros.
Best for: A first multimeter for household and hobby electronics, chosen for its fusing rather than its features.
