The CAT rating is a safety specification, not a quality grade · review
RICOKEY Digital multimeter with stand review
A basic manual-ranging meter covering voltage, DC current, resistance, continuity, battery and diode tests, with a 2.7-inch backlit screen and a fold-out stand.
The bottom line A big screen and a full function list at eleven euros, with the safety specification left out. Keep it for low-voltage work.
A lot of functions, a big screen, and one specification missing.
What the manufacturer publishes
AC and DC voltage, DC current, resistance, continuity, battery testing and diode or transistor P-N junction testing. Overload protection, stated for safe and accurate fault-finding on a range of electrical problems including automotive. A 2.7-inch backlit LCD with data hold. A protective orange case with a built-in fold-out stand.
The specification that is not on the page
Every multimeter carries a measurement category and a voltage — CAT II 600 V, CAT III 600 V, and so on — describing the transient energy it is built to survive at a given point in an installation. It is not a quality grade; it is a safety rating. It does not appear here.
Of the five multimeters in this hub, only one states a category at all. That is a finding about the category as sold, not about this meter in particular, and it is the reason to read the manual before the listing.
Where the fold-out stand earns its keep
A meter lying flat on a bench is a meter being read at an angle, and a meter propped against something is a meter that falls over mid-measurement. A stand is a two-cent moulding that changes how the tool is used.
Availability
On sale at around 11 € on the German Amazon store at the time of checking.
Listed but with no offer on the American and British stores — the reference exists there and nobody is currently selling it.
Not found at all on the French, Italian and Spanish stores, where the buy link falls back to a local search rather than to a page that does not exist.

What we like, and what we don't
Strengths
A 2.7-inch backlit display, the largest screen among the cheap meters here
Includes a battery test and a transistor test, which most meters at this price drop
A fold-out stand, so the meter stands up on a bench instead of lying face down
Overload protection stated
Compromises
No measurement category published — the safety specification is absent from the listing
No true-RMS, so distorted waveforms read low
On sale on the German market only

Questions people actually ask
What measurement category does RICOKEY state?
None appears in the listing. The category — CAT II, III or IV with a voltage — is the specification describing the transient energy an instrument is built to survive, and it is a safety statement. We do not infer one. Read the manual supplied with the meter and follow it.
Is it true-RMS?
The listing does not say so, which means it is an averaging meter. On a clean mains sine wave that is fine; on the distorted waveform of a dimmer, an inverter or a variable-speed drive, an averaging meter reads low.
What is the transistor test for?
Checking the P-N junctions of a transistor for continuity and polarity. It is an electronics-bench function that has largely disappeared from meters at this price.
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.
True RMS · 6000 counts · 600 V · temperature, capacitance and frequency
A true-RMS meter with 6000-count resolution and the widest function list here — 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.
