    Involvement:Expert (understands the inner workings) - Ownership:more than 1 month

    Pros:
    I love this loud sound... you can hear it from rc. I use it mainly fo my gliders so they are not as noisy. Works like other testers, it displays volts for each cell and then total. Manual is simple on the opposite side of tester, so you always see it.
    Cons:
    I always forget which side is for negative side, so it could be more "idiotproof" :-) Also when I carry it in my pock...
