Product review (1 stars): Missing pieces, not a complete kit, works, but you'll need to buy pieces
This kit is not worth the money. It Is missing the foam double sided adhesive,  It is missing 1/2 the screws, and the directions are mediocre at best.

Will this kit work? yes - but you will need to buy 3 extra screws and your own double sided adhesive foam.... Absolutely crap for a "kit" More like a random crap we threw in an envelope that MIGHT be enough to do the job, but for almost $30 I expect a "kit" to be complete.

Not worth it at the price, but will work if stacking is your only option.
