Good ubec but the buzzer is useless.

Buzzer does not kick in until it's to late like other have said so do not depend on that. It's a low receiver voltage only. So flying from main pack if you got down enough to kick this buzzer you already crashed your plane. But that's ok the ubec works perfectly. No issues thus far just makes power. Does its job just fine. If you want a low voltage buzzer for you flight then get the little ones hobby king sells for that specific job. They plug right into the battery pack.

It works. Thats it. Could have used a ESC with BEC instead.
I got it because of that Buzzer feature.

BUT it only reacts when the input voltage Drops below 6V, IT DOESNT WARN YOU if your lipo goes flat. My 4S went down to 2.9V per cell until the ESC's said No.
The Buzzer is also pretty quiet, you wont hear it while flying.

I have no idea how to get the lov voltage alarm feature working, but it's not a problem for me. Removed the speaker to reduce weight. Can deliver the 3A without problem or getting hot.

Very nice little BEC.
I love the fact, that you can select the voltage output simply by switching a jumper and not, with complex flashing.
The buzzer is useful as a mud flavored lollipop :-) Its barely audible in perfect silence, so on the flight field its totally useless. But why you would need a buzzer on a BEC?

inexpensive and reliable 5V UBEC. The buzzer is a little useless for 3S batteries and above, however it does provide a solid spot for wrapping a zip tie around when mount the UBEC.

A must-have when you are either using opto ESCs or models with more than 4 servos. I use them to power my FCs, LEDs. Also a nice feature that you can configure it for two different voltages!
