Review on Rechargeable Voice Enhancer And Audio Sound Amplifier Device For Hearing Assistance, 2 Pieces SA-C5-R by Amy Taylor

Basically, a great idea for dirt cheap, but there are a few foibles: The volume control is tiny and requires a jeweler's screwdriver to adjust; likely I'd set it once and never touch it again. There is no on/off switch; take them out of the charger and they're on and the battery is draining, whether they're in your ears or not. Somebody else commented that one of the units stopped charging, failing to keep a connection while in the charger. Mine did that on the first day. Returned them for a replacement. Fingers crossed .
