See what Magazines such as Fine Homebuilding and The Washington Post had to say...

"Dec-Klip is an ingenious piece of hardware that holds any decking to the joist below without surface nails"
THE WASHINGTON POST

"Dec-Klip fasteners for wood decks eliminate the need to nail through the deck surface. The clips prevent warping and loosening of planks and rot from wood-to-wood contact."
PROFESSIONAL BUILDER MAGAZINE

"Apart from looks, however, these clips should make a deck last longer by eliminating the hundreds of set-nail depressions that collect and hold water"
BUILDER MAGAZINE
