Great Customer Service

Luke Holton · June 2025

I ordered an HY-11 amplifier, but before they shipped it out, a representative reached out to me to confirm the device was suitable for my needs. Im glad they did, because I would've required an adapter. "No Problem!" they responded. "We'll create an adapter for you, free of charge." Thanks, guys! Very kind of you. So glad to have this amplifier to eavesdrop on my whale friends. It also comes with a sturdy and compact case.
