That's why I decided to seriously update my set of diagnostic scanners and try top new products VCM3 from AliExpress.

VNCI VCM3 Car Diagnostic Tool – first test drive
Let me start by saying that this scanner was the first one that came into my hands. I ordered it as part of a promotion, delivery took about three weeks, the box arrived intact, with a neat case inside. I chose this model because it supports CAN FD and DoIP - without this, modern Ford and Mazda are simply unreadable.
The first turn-on surprised me: the drivers installed quickly, the software installed without dancing with a tambourine. I connected it to a Ford Mondeo - and what a miracle it was, I saw all the errors in real time. By the way, the battery test also works, although I doubted it.
Pros: – Connects clearly, does not hang; – Support for new protocols; – The price is two times lower than that of analogues in the Russian Federation.
Cons: – The instructions are in English, I had to figure it out myself; – The software is original, but updates must be searched for manually.
Overall, this is my personal favorite of the bunch. Top vcm3 . It works stably and costs adequately.

VNCI VCM3 Diagnostic Scanner for Ford Mazda – a reliable backup
Next I ordered a more compact version VNCI VCM3 to have a spare device. Arrived quickly, a little less than a month. Why did you buy it? Because in the reviews many wrote: if one is buggy, it’s always better to have a second one.
I will say this: he works no worse than his older brother. I connected it to the Mazda CX-5 - it reads both the automatic transmission adaptation and all the blocks. IN vcm3 review I can note that this particular version identifies blocks by DoIP faster than the first.
Pros: – Fast response; – No problems with installation; – Supports IDS.
Cons: – No USB cable included (bought separately); – The case is a little simpler than expected.
For the price - an excellent choice for those who want to try vcm3 buy no overpayments.

VCM3 VCM III Professional Tool – “heavy artillery”
This scanner is marketed as a professional tool, and to be honest, it lives up to the name. The case is massive, the build quality is good, it even comes with software and a disk (although who has a drive these days?).
I connected it to a Ford Kuga 2019 and I really felt the difference. Deep diagnostics, coding, flashing modules - all this works without failures. IN vcm3 reviews Users wrote that it sometimes freezes, but I didn’t experience this.
Pros: – Maximum functions of all models; – Support for UCDS Rotunda; – Reliable operation.
Cons: – The price is higher than others; – The software requires a stable laptop (it hangs on a weak one).
This thing is for those who actually work with cars every day. It may be overkill for garage needs, but I'm happy with it.

UCDS Rotunda Diagnostic Interface – “narrow specialist”
Now about a rarer purchase - UCDS Rotunda . I’ll be honest: I ordered it out of pure interest, I wanted to compare it with VCM3. Delivery - about a month.
I connected it to the Focus RS and Fiesta - and here the interface proved to be excellent. Great for encoding and updating blocks, but not as versatile as classic ones vcm3 buy solutions.
Pros: – Perfectly tailored for Ford; – Fast work; – There is access to experimental functions.
Cons: – Not universal (Mazda doesn’t hold up); – Support is limited.
As a result, it’s a good tool for Ford fans, but I wouldn’t choose it as a primary scanner.

VCDS HEX V2 OBD Tools – “German guest”
Yes, yes, I know that this is not really about vcm3, but it was in the top, and I took the risk of ordering. I wonder how it will behave with the VAG group.
I connected it to the Skoda Octavia - and, frankly, I was surprised. It works at the level of the original VCDS, although it cost three times less. IN vcm3 review It can be mentioned conditionally, but as a separate instrument it is simply a godsend.
Pros: – Full access to VAG units; – Reliable connection; - The price is great.
Cons: – Only for VAG; – The software takes some getting used to.
If you have both Ford and VAG in your garage, then this is a must-have.

Alfametrix Diagnostic VCI is an interesting newcomer
Last on my list - Alfametrix VCI, which is positioned as an alternative to VCM3. I bought it out of curiosity, and the price was good.
What can I say? It works, but not as stable as we would like. I connected it to a Ford Fusion and it does diagnostics, but the program crashed a couple of times.
Pros: – Cheaper than original VCM3; – There is IDS support.
Cons: – Sometimes loses connection; – Software updates are rare.
I can call it a backup option, but I definitely wouldn’t make it my main scanner.
$704.5Results: is it worth buying vcm3 on AliExpress?
That's all mine Top vcm3 reviews . To be honest, I didn’t even expect that you could get such working tools for that kind of money. I kept it for myself personally VNCI VCM3 And VCM III Professional Tool — they really cover all needs. The rest are either too narrow or according to the mood.
Is it worth ordering? Yes, if you are willing to tinker a little with the installation and drivers. The price is several times lower than in Russia, but the functionality is almost the same. So my verdict: vcm3 buy on AliExpress - this is a really profitable step, especially for “garage fans” like me.
