I'm confused here. In reviewing the reports, I see that Horizon's bottles are off an average of -.70oz, yet only one exceeded the allowable tolerance. The bottles weigh almost 17lb, which is 2lb more then the other suppliers and at the high end of the scale. Yet, they failed and the product has been pulled. The other two suppliers also had variances that exceeded the allowed tolerances, yet they passed. They offer only 15lb propane vs Horizon's 17lb. How is this? I'm so confused.....It just doesn't seem equitable.
