What we liked
- + Works with F3, F4 and F7 flight controllers for broad compatibility
- + 2pcs let you equip two quads or keep a spare
- + iFlight quality makes it a reliable basic buzzer
Trade-offs
- - No independent battery, so it will not beep after a battery ejects
- - Bare buzzer needs careful soldering to FC pads
