I got this mainly to test for bad mosfets. I saw how versatile it is and grabbed all kinds of things to test and it worked for most components. The shocker is what’s in my picture. That’s a 4000uf 400v capacitor and it read to within 1% of my Fluke 289.The Only issue I have is that the leads that come with it are tiny and fragile

Socket latch doesn't seat in quite all the way but still works fine and for a $20 meter I'm fine with that.

Tested with several transistors, capacitors, diodes and resistors. Every time the tester responded perfectly with very slight variations within 5-10% from the datasheet values.

PROS: The tester itself is nice. Quickly tests transistors, resistors, capacitors, etc. Results with resistors and capacitors seem good, though I don't have a different reference. Identifies base, collector, emitter reliably.CONS: The test leads do fall apart after a while. One pin broke off. It's been 6 months of light use, but maybe that is expected. Whatever. (Just realized that I can plug TO-92 transistors directly into the unit - no wires required.)WORSE: The transistor Vf results are very inconsistent. Tested one transistor.With the test leads. Vf=1.2V.Plug directly into unit (no test leads) Vf=0.987V.Switch battery (still no test leads): Vf=0.782V.Can't really rely on this measurement.

I figure the device itself could be (likely is) good, but the test contacts are so unreliable that getting a good read is a matter of chance. Not what you want in a component tester. Going to return this and hope a different manufacturer has better QA processes.For starters, not related to the contacts, it mis-reports the battery voltage. When measuring the battery voltage independently while the device was operating, the DMM shows 8.6V (with the battery showing 9.4 unloaded). The tester says the battery is OK at 7.5V. That aside, the battery compartment is just a little too small which makes it hard to open or close, and uses the dreaded 9V clip-on-a-wire which is always good for some cursing when it gets time to replace the battery.The ZIF socket is separate and gets inserted into the 4x8 header on the front. The fit is not what I would call confidence inspiring.I took a few known working components and inserted them. An LED got correctly identified the first time. I moved it to different contacts with the same numbers and now it shows as a capacitor. Moved it to different contact numbers and it comes up as "no or bad". A 2N7000 MOSFET was sometimes identified as 2 diodes, a few times correctly, sometimes as "no or bad".

Works great but really needs longer test leads!

I needed to check a couple of hundred transistors because I'm building this crazy clock that uses only discrete parts. I could see where troubleshooting it would be a nightmare if there were any bad components. I got the diymore transistor tester so that I could check all the transistors and diodes before I soldered them into the board. It turned out it was a very good thing to do.I have not used this for testing capacitors or resisters, but it does a great job on transistors and diodes. The only thing that seems off about it is that the battery voltage reads 7.4 volts with a fresh 9 volt battery. It's a great tool to have in your toolbox.
