Decent if you want a ballpark value, but only sometimes. It doesn't give accurate readings and definitely doesn't give consistent readings. I know not all of the transistors I measured have the exact same gain, and inductors never measure properly even though it's supposed to be an L/C/R meter. I don't trust it and will upgrade to a real meter when I get the chance.

Great device to have in your home lab
Works great. I tested a lot of different parts (R, C, L, Diodes, Bipolar, FET) identified most of them well.
I compared R and C readings to my Fluke 87V and they are spot on.
Some Devices it couldn't identify:
- super caps. It couldn't identify a 1.5F nor a 50F cap I tried.
- SCR It failed to identify some SCRs I tried.
Make sure electrolytic capacitors are fully discharged before testing - otherwise you might burn out the tester!

best idea for low low cost
this meter work as good at high prived on like peak that cost over a 100 bucks
make your own case and get a 9 volt battery from local dime store...
this unit works to fix stereo amp transistors and caps that what i got it for

This is a really neat little gizmo! It works really well. It is pretty accurate, good enough accuracy for hobby and experimenter/technician use. And the price is good. It comes just as you see it in the manufacturer's picture. I added a battery holder clip and used some standoffs to mount the board and battery to a piece of hobby wood just so it wouldn't sit on the backside of the PCB and the battery wouldn't be floating all over the place.

This is a very cool gadget.
I teach college electronics. I definitely want some of these in the electronics lab. I've tried it with a number of various parts and it never fails.

Great transistor tester / component checker / meter.
Fantastic little gadget. I finally have the ability to sort components by similar values, easily check capacitors, and match transistors to each other. I need to design a printable housing, but it works fine as a standalone.

Some quality issues, but worked.
Works, but very cheaply made. The release arm popped out the first time I used it, and the ZIF socket seems to have issues rebounding. But it more or less worked on a handful of components I tested it with. You may find various 3d printed cases on thingiverse that look like they may fit, but probably not since there are some variations of this out there. You really will need to find something to hold it in safely.

Great help for electronic builds and repairs
An inexpensive tester for checking new components and for repair work. Not the most accurate, it's easy to figure out the difference.

Great little sorter
Neat little unit. Worked first time powered up. Need this to finally sort thru my years of various transistors and other components. Too bad it does not have an enclosure.

A neat hack, may not be for everyone
This thing is cool! It's a really neat hack at a very reasonable price. It doesn't come in a fancy case, so it's a little hard to store, but it works and is very handy for identifying unknown components such as resistors or caps. It may not be for everyone since it is not enclosed in a case.
