Repacking is a Pain
I've done it twice — once on a belt pack that got the "jerk to infl ate" tab stuck in a door jamb. I repacked it wrong even after poring over the directions. Don't ask me why I tested it. I repacked a hydrostatic unit correctly in about 30 minutes. Practice makes perfect, but it's expensive, costing between $15 for a manual and $80 for a hydrostatic model. Oh, and you can infl ate them all with your mouth too, but I'd get all fl ustered around Pamela and have trouble puckering up.
