Review: Cheap, easy, and low profile. What more could you ask for!? - The voice changer worked out great! It does not include a speaker, so remember to get one. The board is clearly labeled, and the instructions inside help you map the components. A soldering novice could easily complete this project. The finished product is very effective, just pay attention to the mic sensitivity adjust. Definitely a fun project, and great for costuming. Note that the components are soldered in individually. This makes it pretty easy to put speakers, mics, buttons, and volume knobs in more convenient locations. Just a bit of wire, and you're set.
Review: Takes 4 hours to build - After 4 hours of hard work building the circuit, the item did not function as expected. I have experience with soldering, but for whatever reason, it did not work as intended. The lights and sound came on which means I wired everything correctly, but the mic did not pick up any input so it sounded like just a un-tuned radio. Great learning project for an inexperienced child. Also, the battery and speaker connection instructions do not make sense to use tabs. Not sure what that is about.

### ⭐⭐⭐⭐⭐ Cheap, easy, and low profile. What more could you ask for!?
*by D***N on July 16, 2014*

### ⭐⭐ Takes 4 hours to build

After 4 hours of hard work building the circuit, the item did not function as expected. I have experience with soldering, but for whatever reason, it did not work as intended. The lights and sound came on which means I wired everything correctly, but the mic did not pick up any input so it sounded like just a un-tuned radio.

### ⭐ Poor Quality
*by D***E on September 10, 2017*

While I found the directions laid out very well - the quality of the PCB is very poor. I am a EE and use a soldering station frequently. I have never seen solder pads pull away from the PCB so easily. I lost 3 seperate copper pads which rendered my board useless. I cannot recommend this product. Too bad as I really wanted this for a Halloween costume.
