Philips Norelco HQ8 Dual Precision Heads

1) Amazon's picture, and the box the product comes in, show a single head assembly, with three heads mounted single holder, ready to snap onto the shaver as one piece. What it contained was a total of six separate loose pieces--three blades and three grills--that fell apart and scattered when I opened the package. 2) No instructions. When I pay $28.99 for a genuine Norelco part, the least they could do for that price is include an instruction sheet in it. 3) Installation is not difficult, but not obvious, either. An instruction sheet IS needed. I couldn't find instructions linked from the Amazon catalog page, nor could I find one on the Norelco website. Yes, after a search of the house I located the original shaver directions, and I am glad I did it, as I would not have successfully figured it out without the directions. 4) Norelco's website calls out HQ8 as the replacement part, and Amazon's catalog page shows it as "Amazon's Choice." I am annoyed at myself for overlooking Amazon's note, a little lower on the page, that "There is a newer version of this item." But I am also annoyed both at Amazon and at Norelco for not making this clearer. An outdated item should not be an "Amazon's Choice."
