Customer Reviews (5.0 / 5 · 5 reviews)

Aurora ★★★★★

Took it out of the antistatic bag, wired it up to a 5V rail, and got a clear, steady tone the instant power hit it. For the price, having that 3.5–5.5V tolerance means I can swap it between different projects without worrying about frying it. Exactly what my alarm circuit needed.

Hazel ★★★★★

Plugged this into my breadboard project and it started buzzing immediately — no fiddling with code or extra components. The 3.5 to 5.5V range made it easy to power from a standard Arduino pin. Exactly the reliable tone I needed for a simple alarm circuit.

Lily ★★★★★

My last project needed a constant tone without extra code, and this little buzzer nailed it straight out of the box—just applied 5V and it beeped immediately. The 3.5V lower limit gives nice room to work with weak batteries too.
