## Customer Reviews

### ⭐⭐⭐⭐⭐ Works great
*by P***J on 6 June 2024*

The piezo does exactly what is supposed to do. I used it to make cigarbox guitar pickups from them.

### ⭐⭐ Waste
*by Н***Г on 15 October 2022*

Your opinion to buy

### ⭐ Not generating enough voltage
*by R***J on 6 November 2023*

Some of the supplied piezo is generating 1 v but most are generating very very low in the range of 0.1v. Worst quality.
