Every componenet of our jet had its adcantafes and disadvantages - of course its something that could go bad (although probably unlikely) but it also gives you 100% battery monitoring. its your choice - thas the fun thing about this hobby. just thought i'd sahre the face you can buy a 9$ unit which is much nicer than the 25$+ units.

BTW you could always wire up a proper connector to this unit and use it as a no load external voltage tester.
