    win-win

    these kits, i strip of the nuts, and sell the lines alone. even then i beat the others in price and have the perk of additional sales of the nuts separately

    Don't ship products that bend in a bag !

    shipping was not that great, fittings were removed from sealed kits to fit in a bag, some tubing got bent in shipping, will have to fix before use. This could have been prevented by putting it in a box!
