Great for the price
Wanted a voice activation solution outside having to come up with a Java solution in Android, but didn't have enough resources on ESP32C3 to handle voice recognition well. Settled on a "whistle trigger" (using Goertzel constants; frequencies matching whistling on a b-flat scale triggers current on different I/O pins) instead. This worked out reasonably well, though I was foiled again by ceiling fans. Struggled to get consistent readings; eventually realized I had a ceiling fan pointed directly at the microphone; things were fine after turning off the fan.

Amplified electric condenser mic’s
Received In brand new perfect condition. Well packaged items. These amplified condenser electric microphones didn’t work well for my project that I was working on. With that said, it’s probably me more than the product. I’m sure they could work ok on other devices. They are pretty nice . It’s amazing that you can adjust the mic gain with a very small pot located on the bottom of the board. Maybe I’ll have better luck on some future projects. Good luck!

Works great! See review for pre-emphasis circuit mods
Sounds great, works well. I modified the circuit to provide a high-pass "pre-emphasis" for use with an AM transmitter. Circuit below

Works exactly as described.
Had no issues getting these to work for my project. Have bought others and they wouldn't work. I've used 3 so far and not one problem.

Worked well with 3.3v logic
Solid little microphone without too much markup over direct-from-china shipping. I used them for capturing audio signal levels and the sensitivity and calibration have been good on each of the ones I've tested, but I can't speak to their frequency response.

Some components bad
Two were bad, but it was relatively inexpensive so i just ate the cost

way smaller than pictures which is good in my opinion
worked well for my project for ECE class i would recommend i soldered the connector on just fine. i will say who ever created the pictures for selling is wildly incorrect about dimmensions its ways smaller than advertised which i say is plus i thought i was getting a clunky massive mic but it was many magnitudes smaller than the pictures and fits on bread board well. good entry level mic for the money.

Great little amp
I've used these in a few 3D printer projects and their easy to solder and incorporate into a program.
