Review on Guppy Listening Amplifier Professional Collector by Brandon Peters

Revainrating 1 out of 5

Can't even pull out something that feels 50/60. Not happy with this device.

Very easy to use but the sound is not very good. It's like just turning off the radio station you're listening to.

Pros
  • Powerful noise detection system, ultra safe frequency control reduces unwanted background noise.
Cons
  • High price
