As a tool, it does the absolutely necessary, it shows whether there is a voltage or not. This is done only visually by lighting up the corresponding voltage measurement light. No notification sound, no front flashlight on the probe, and the screen seems to be lacking based on the photo, but that's also a downside because it is a professional tool. The button it has is not for testing the circuit continuity since it doesn't have a battery, but to test the leakage relay, if it exists.
In one sentence: it's a good tool but for the double and extra money, you can get a better one.

Simply unacceptable, it does not indicate any tendency if you touch it at one end and it does not have a buzzer, simply unacceptable, I wasted my money for nothing!!!

It is very good, high quality, affordable, and beautiful from a reputable company in the field.
The front naked eyes are small because they are covered by removable plastic parts that you can take off to test difficult areas such as a tight socket where the plastic does not touch the corresponding prongs to make contact.
The plastic parts, which are there for added protection, are useful for testing panels, motors, exposed wires, etc.
Personally, I really like it, time will tell if it will withstand

The iron tips in front come out 2 millimeters! When you plug it in, it doesn't touch anywhere! You can't even wrap cables around them and provide power. If you remove the plastic (you have to cut it, they don't come off), you have very thin tips that still fit in the socket! Everything else is good. Get it.
The plastic protectors in front of the tips are not removable! They are not screwable or lockable. Without the protectors, the tips become so thin that they break inside the bag! They pierce through everything.
Yes. It is beautiful. To hang it around the neck. If I have to make strange movements just to find the point where the blades touch in order to check a simple socket, then what should I do with this accessory?
The cable is not stable at the points where it enters the plastic. It rotates freely! It's just a matter of time before it breaks.
I didn't expect such poor construction.
