Too good to be true.
The YT video doesn’t even include a link for ordering it, nor any additional information.

From YouTube where I saw this thing:

Free shipping on orders over $39.00 (US). Notice that if you order four of them (Buy 2 - get 2) you still have to pay for shipping; whatever that may be. And no - I haven't considered buying one.

 

Seems too simple to me.

I don't even need a tester. I just look for the smoke.

 

I watched the video, it was interesting . As for the comments: Not one bit of it was spoken to be understood!! The guy talking spoke WAY TOO FAST!! There may also have been an accent issue, I could not tell. TEXT IS ALWAYS BETTER THAN SPEECH FOR EXPLAINING ANYTHING!!!!!! The possible exception would be singing!!
As for that "tester", What property of the inductors was it testing?? Continuity can be checked with a simple beeper, or an ohm meter, neither tells me what the inductance is or if it has any shorted turns.

 

The best tester I have is IP. Hence you cannot have it.

I'll bite: what's IP?

Certainly there are folks more skilled than I am, no question about that! BUT that was not what I inteded to be asking about. An inductor has properties of INDUCTANCE, Resistance, self resonance, and power handling capability. And probably a few others that I missed. What I think I saw was "two green lights" on the probe. That could be indicating continuity, which I did not mention. RESISTANCE, which includes continuity, is simple to measure, but actual inductance, and "Q", are usually quite important.

 

I don't get it either. I see it touch the top of the inductor, press button, green light. Then touch one lead of a diode that's clearly part of a 4-diode bridge, then a few random parts on a PCB. All green lights. Nothing ever fails! it seems to be some form of near field detector... maybe its showing there's AC present. Maybe, in the case of an inductor its picking up the E-field of the switching current so showing that your buck/boost/whatever is functioning and the inductor is neither short nor open.

But an inductor tester it is not.

With all the guff on testing standards it smacks of a scam.

I have found that there are very few who know how to make a decent Youtube instructional video, my main pet peeve, apart from rapid fire talking, is when using an instructional video, they use the mouse as though they are in a race, and any selection appears as ablink of the eye!!
One of the exeptions is a guy who shows how it should be done IMO. He also happens to be Dutch, in spite of English being his second laguage, I find his video's excelent. He has also written some good books on his selected subjects.
His name is Bernard't Hooft

 

Think about it this way: you unplug a power supply from the wall outlet and test the components. All of them are bad and need to be replaced. Just an analogy to illustrate how lame idea of one-LED-all-sorts-of-components-tester is.

 

Like I said, I've seen it and just had to ask. I have no intentions of buying such a device. Perhaps it does work somehow. I still don't think I'd need it. Other more tried and true test methods would be the way I'd approach a matter.

I suspect this video is a bit of hog-wash. Though I don't know what "Hog Wash" is. Still, they're selling something. And the ratings seem to be missing. Is it 1 star out of 5? 5 stars out of 5? Or somewhere in-between? I just had to ask.

 

Though I don't know what "Hog Wash" is.

"Hogwash" is an informal English term meaning nonsense, rubbish, foolish talk, lies, or worthless claims. It's often used to dismiss something as untrue or ridiculous, similar to words like "baloney," "bunk," or "claptrap."

Examples:

• "That story about him winning the lottery is pure hogwash."
• "His excuse was nothing but hogwash."

Origin

Literally, hogwash originally referred to the kitchen slops, scraps, or liquid refuse (swill) fed to pigs — basically garbage for hogs. This dates back to the mid-15th century (Middle English hogges wash or similar).


Over time (by the 18th century), it extended metaphorically to mean cheap, low-quality stuff (like bad liquor), and then to "inferior writing" or any worthless/nonsensical ideas. The figurative sense of "nonsense" has been common since at least the 19th–20th centuries.


It's a colorful, somewhat old-fashioned expression that's still widely understood and used today, especially in American and British English.

Yes, simple and pure snake oil.

Notice that half the time he's touching a part of the body of a component!

The very notion that there is ANY go/no-go way to tell that an arbitrary component in an arbitrary circuit is good or bad is patently absurd.

vandveuser16776 IS CERTAINLY CORRECT!!!
The properties and effects of different components makes a single test concept very unlikely. The one possible exception that I have seen was a clock radio that had seen the full effects of a direct lightning strike on my 58 foot tall tower, and then penetrated our house. The effect was that every component on the PCB, as well as the power transformer, was damaged or burned. No test eauipment was required, only observation.
AND, in post #11, MAX repeats my thoughts completely!
BUT, a VISUAL INSPECTION can certainly notice burst and burned components.
In addition, I have seen testers called "ANALYSTS" that are intended and capable of verifying every citcuit of a radio receiver for correct operation, when used by a technician. The theory is that if a system circuit functions correctly, that all of the individual components must be OK.

 

There will probably always be dihonest individuals misrepresenting systems claimed to perform better testing and diagnostics than is possible. and unfortunately there are folks who may believe them, and spend money and purchase those devices.
Of course, with a good digital multimeter a good service person with adequate knowledge CAN locate failures. BUT the important tool is the knowledge and the skill, rather than the equipment.

Knowledge is the indispensabel tool. Without knowledge, all the test gadgets in the world give ZERO diagnosis chance to a clueless repairman, nay, damage healthy components or the tool or both if set to wrong range (i.e setting multimeter to amp and test a resistor on a powered circuit), but knowledge is just the beginning. Experienced repair techs are 100 times faster than beginners. Over time, you develop the intuition that whisper to you "test this one first" and the first one you test is the faulty one.

 

nothing says "reputable" product like promotional video where comments are turned off...
and nothing says "safe" product like one where you get to probe high voltage circuits such as PSU, while holding bare PCB in your hand.
any such videos should land creators in jail.

I didn't even notice that the comments were turned off since I almost never look at them -- they are usually worthless griping or venting, often about completely unrelated things. But, you're right, turning off comments is a pretty good sign that the creator knows that they are going to get hammered mercilessly because they are pushing pure crap and that WILL attract LOTS of very pointed and relevant comments.
