Well, the Voltwatch2 does exactly what it says it will do and costs $11.99. Certainly you should get more for three times the cost. Is all that necessary?

Three of my planes have two batteries each. That, together with my Voltwatch2, saved my Venus II. One Voltwatch2 per plane. It is just a matter of taking the time to make an observation to see the condition of the batteries and acting accordingly. With out the Voltwatch2, I might have taken for granted that I had plenty of time to fly a third or forth flight, which just wasn't the case. You see,one of the two batteries failed in flight.

If I had one battery and it failed in flight, Voltwatch, Voltmagic, or any other gizmo would not have saved the plane no matter what. The battery failure occured during the third flight of the day on that plane, and I found it by my routine post flight observation of the battery condition using voltwatch. My routine is to check the battery before and after each flight, as I did that day. It (Voltwatch2) did just exactly what it was designed to do.

I don't doubt that the other gizmo's are fine, but to make a comment as above, is simply not productive and distorts the facts. Voltwatch does what it is designed to do, as I'm sure the other gizmo is. I like and trust the Voltwatch.
