All the parts assembled fine - the components and the PCB were of good quality. When I tested it however, everything worked well up to about 5 MHz, then the display became erratic and did not display any frequency above that. In fact, the frequency display went lower when I injected higher frequencies with my RF Signal Generator (which works well with a commercial frequency counter). I thought the IC may have been defective, so I ordered another kit and on arrival replaced the original IC with the newly arrived one - no change. So I have a frequency counter which works great from 100Hz to 5 MHz, but I need it to read up to 22 MHz. I don't know what else to do to it to fix it. However, I will eventually build the second kit to see if it works as advertised. Until that works properly, naturally I cannot recommend it to anyone.Read full review

Reportedly the original design and code is by DL4YHF (Google: DL4YHF counter). This kit went together smoothly. No missing parts (one extra 22pF capacitor), worked at power up. Took about 90 minutes to assemble, YMMV.

Only one kit of 3 worked, the other 2 needed new counter microchips.

Was a little skeptical but purchased anyway. And then it worked.
