Got this as a present today. I really hate added gear in my field box because the weight adds up but this thing is the best way to know whether it's safe to fly on a battery pack. I dropped my cheapo and my wife bought me this on John Beech's recommendation [thanks Rhonda!]. Anyway, I've put this one into a foam receiver wrap for protection. Recommended!

I bought this on John's recommendation within the article on determining how many flights I could obtain safely on my battery pack. Works great and I'm happy I got it.

I've got one of these in my helicopter field box. Now I've got one for my model airplane field box also because I feel naked without it.

I bought this battery tester and used it once before returning it because my buddy got a cheaper one off Amazon and it does the exact same thing. Don't get ripped off paying for a fancy label.

Had it about a month before it crapped out after I dropped it. I don't know what the warranty is. Hate eating this but it's not Futabas fault so my tough luck. Worked good before this :)
