    good product, both to measure the battery level as to warn when this esgotanto. Recommend! More safety and comfort in flight. Also retains the useful beteria longer and prevents damage due to excessive use.

    I bought it for my Tricopter, and I was suprised with the result. Pros: It works as it should and buzz alarm comes on with the setup voltage. Alarm sound level is quite high, it should not be a problem to hear it from long distance. Cons: Power consumption is not listed in the specification.

    Impression:Worthy purchase;

    Bastante bueno. Le fataría algún tipo de protección para que se pudiera sumergir, ya que el uso es para una lancha de rc.

    it's my 2nd buzzer i buy. the first died after one week. it's really loud so you will definitely notice when the batteries are low. tested with only 1-3S batteries. I hope this one will last longer.
