It does exactly what it describes, I use it professionally as a maintenance technician in a large building and it is very reliable, unlike a previous one from a well-known electrical tools and instruments company.

sturdy like a tool!
the only negative is that in the voltage sensitivity indicator the colors work the opposite way from what is mentioned in my model
otherwise very good

Very good! I was expecting a stronger sound, the cheaper one from the same company has at least 3 times stronger speaker!

It is a much safer test screwdriver.

This one can also detect magnetic fields, magnets.

The beep it has is faint - but you can also see the light.

The flashlight it has is satisfactory.

The battery cover at the back has the known problem of not making good contact with the side part of the battery, you need to close it tightly or put some aluminum foil.

It is definitely well-made, heavy, and looks high-quality.

It does not detect anything significant on walls - the circuit must be closed and voltage must pass through to find something.

It also has two levels of current detection - it starts from 12 volts or from 90 volts. At 12 volts, you can even detect USB.

And the closer you are to the source, the higher the frequency it detects.

It is 100% better to have such a tool for testing - or one like the UT18C (or even both)

It's fine for its price..a bit big to have it in your pocket but as we said...for its price, it's just right

The truth is that I didn't expect it to be reliable! In the end, it is much better than many other products on the market, and even better than well-known companies.

Very good. I recommend it...
