A fault code names a symptom, never a cause · review
A plain, plug-and-play engine code reader whose selling point is protocol completeness — the maker names the protocols explicitly, which several tools at this price do not.
The last word Bought for what it does not need: no app, no pairing, no subscription.
A self-contained code reader with an LCD screen and a cable. Plug it into the socket, turn the ignition on, read the codes, clear them if you decide to.
Most listings at this price say “works with all cars after 1996” and stop. Strex names the protocol set, including KWP2000, and that specificity is the difference between a tool that connects to your car and one that shows a dash. It is the single most useful thing published about it.
Engine system only, no live graphing, no service resets. A reader of this kind answers one question — what code is stored — and answers it without a phone.
The size of its code description library, and whether it is updated. Neither changes what the tool can reach.
Not found on the American Amazon store, where the buy link falls back to a local search rather than to a page that does not exist.

A car answers on one of several OBDII protocols, and a reader that only implements some of them will fail to connect on the cars using the others — while looking identical in the listing. A maker who names them is telling you something.
It is more reliable and less capable. It boots in seconds and works with a flat phone; it will never show what a good app shows on a large screen.

The figure is a floor, rounded by Amazon, and read through Keepa — it says what buyers picked, not what a maker claims.
Specifications: the manufacturer sheet for garage tools and the matching Amazon product page. Prices and availability: Keepa. Every figure on this page names its source.
Engine system only · 2.5 ft thick cable · no batteries needed · maker states ABS and airbag are NOT supported
The reader that has been on this shelf for a decade, and the one whose listing is most explicit about what it cannot do: the maker states in the first line that ABS, airbag and SRS codes are not supported.
Best for: The glovebox tool for an older car, where reliability matters more than features.
Engine system only · 2.8-inch color screen · live data · battery test · 8 languages
The cheapest way to stop guessing at a warning light: engine codes, freeze frame and live data on a color screen, with a battery voltage test thrown in — and no access to ABS or airbag, which the maker states plainly.
Best for: A first reader for a household that wants to know what the light means before phoning a garage.
Engine, ABS, airbag and transmission stated · 7 reset functions · Android 8.1 touchscreen · 32 GB · lifetime free updates stated
The tool where the update policy is the headline: LAUNCH states lifetime free updates on a four-system scanner with a touchscreen and seven service resets.
Best for: Someone who works on several cars, or on one car with an ABS light.
