Review on Advanced UZIMO Listen-Thru-Wall 🎧 Microphone Amplifier System with Enhanced Sensitivity by Justin Pavelko

I like this product, it works well. I recommend attaching the contact mic to the wall with a dab of hot glue, being careful not to use too much glue and sticking the center needle in place. This reduces the extra noise of your hand holding it. ALSO! If you look from the side, you will see that there is a hole for the SD card. A normal SD card will not work. There is one other thing for this device that you can record with. breaks into the opening i had to look for aliexpress. And it only costs 10€ plus shipping. So I ordered these and wait, then I can update this review.
