Worked like a charm! Read the directions! Lights go out when points open. It measures impedance, not continuity.

This device works as advertised. The Green and Red LEDs light up prior to the ignition point trigger and they go off exactly at the ignition point. When LEDs are off, there are different tones for each channel that will sound, so it is trainable to the users ear which channel is firing before the other. Setting up dual magnetos is straight forward. This is a fair priced easy to use system.

My experience with the magneto synchronizer buzz box was like attending a comedy show for engines! Setting ignition timing on my aircrafts piston engine was never this entertaining. The buzz box not only synchronized my magnetos flawlessly but also gave me a hilarious soundtrack of buzzing noises, making the whole process feel like a high-stakes game of musical chairs for spark plugs. Who knew engine maintenance could be this much fun? Highly recommended

My name brand unit quit after 30 years. This one is off brand but looks identical. Hope it goes 30 years. A little pricey for what is inside these things.

This is the second tweeter I have purchased. First one quit working after 6 uses. I found it difficult to get it to work properly. I thought it was just a lemon, so I purchased another one. Dumb mistake, second tweeter just as unreliable as the first. I have now gone back to the traditional tweeter box to save time and reduce frustration. Beware!
