Excellent, high quality 👌.

Very good purchase. The voltmeter looks of good quality, both the device and its accessories. I liked that it comes very complete and looks sturdy and durable. For the price, the functionality it offers is very good. I still need to test it and take measurements, but so far I am very happy with the purchase. I recommend it.

Cora Wuckert

I feel like I got a good deal at a reasonable price, and it's useful for checking whether the audio capacitor and fuse are working properly.

Product appears to be well-built and works as intended. the leads could be better though, especially the temperature one.

Measures very accurately and quickly!!! i tested it on resistance, capacitance, and inductance. the best multimeter!!

The multimeter is working perfectly, I just found the LCD a bit dark, making it necessary to turn on the LED backlight to see better, but other than that, everything is fine. I recommend the seller and the product!

Great quality multimeter, I already have the T21D and now the T21L for inductors. I recommend the purchase and the seller.

Compact multimeter, good quality. Everything is as described in the product description. The probes are not the most sensitive, it's better to replace them. All functions work. Runs on AAA batteries, which is convenient. The screen is easy to read. The flashlight is quite bright. Glass fuses are included, with spare ones in the set. Overall, a positive experience, I recommend it. Fast delivery.

Apparently a great product, I tested most of the functions and I am satisfied. As you can see in the photos, the build quality is good, it has a magnet on the back to attach to an iron surface. The probes have a reasonable quality (they don't seem as good compared to those of other multimeters I have, but for the price it was well worth it).

I used to carry it around with me at work for a year, and it had its own share of problems.
There are magnets and batteries that have never been used, so I returned them after switching jobs.
I had to buy a new one, so I looked into Hiochi and just in case, I checked Ali and found this one, so I bought it. It's pretty good for the price, I recommend it.

It's quite heavy even without the battery. It seems to be of excellent quality. I will test it and come back with final feedback. Thank you ☺️

Everything is fine. I wish there was a cover, even if it cost something.

E
Ethan Romaguera

I bought the multimeter mainly to measure battery charge and to search for a power thief at the station. So far, everything is working.

M
Marry Lakin

The order arrived as described in the listing.
The multimeter does not include batteries, so I bought and installed the batteries and have been testing the multimeter.
It works well for measuring continuity, voltage, resistance, capacitance, and inductance (I did not test measuring current).

The only two negative details were that I don't know how to open the multimeter in order to change the fuses in the future, and the "NCV" function cannot detect live wires inside walls (walls made of stone material).

Roselia Robel

The quality is good and the price is excellent.
