All 10 pieces of electromagnetic buzzer (not piezo) are working great, loud enough, work from 1.8V to 5V with almost the same volume and slightly changing frequency. Current consumption is around 24 mA at 5V. Positive (longer) terminal is clearly marked by transportation seal on the top, the seal should be removed after installation to get full volume sound. Solid seller, solid product, reasonable delivery and price. Will buy more, definitely recommended.
