I was skeptical of the low prices, but Wayne told me these were really good packs, since I occasionally fly with Wayne I figured could try them out. They have been great. I put these in my flying wings, they are buried in the plane, so I tested the first pack and was surprised to see it actually supplied the full rated charge. I used to pay twice this price for my packs, and these actually test out better then those name brand packs.
