Very happy with result
Used this jig, and Kreg deck screws, while building a roughly 8ft x 8ft treated lumber deck extension to our pool. Very happy with the results. A couple tips would be to have two drills to save time switching back and forth between the drill bit and screw driver. Also I purchased extra spacers, as three that came with package did not seem like enough.

A Worthwhile purchase
Very good idea, and a good, though not great, product. The screw heads strip too easily, and the drill and driver bits tend to bind a bit in the jig if they are at all dirty. Having said that, this is a tremendous time saver, delivers very nice results, and was worth the money. The stainless steel screws are pricey, but come highly recommended by my contractor friends. Buy this jig, but learn how to finesse the screws into place.

Every deck I make will be using this Gig
Finished building an amazing deck on top of a mountain using treated 2x8s for the decking. So so happy with the Gig, all decks should be done with this. Didn't use their overpriced screws and used standard "side" screws from my hardware store, so easy, drill the hole, remove the gig, place the screw and in it goes, clean and easy with no wood movement so far. Every deck I make will be using this Gig. Thinking about it.... Just buy it as it works with just a bit extra work but 1000% better looking and I feel it's a better connection too.

For Meticulous DIYers, the results are A+++
If you are a homeowner and want a deck essentially free of fasteners, this is a valuable tool. I have several Kreg jigs and the step-drill bits used for the pocket holes can be notoriously prone to breaking, but that was not my experience with this jig. It's time-consuming and you must be willing to put the work in to it, but the result is a surface free of screws, which means no exposed metal and no nail pops. For me, this was a deck rebuild, and I decided to go with pressure-treated wood rather than composite, as the latter required more structural support and was prone to warping, discoloration, and being hot under foot. Following the instructions, re-decking my 8X12 deck was kind of tedious yet free of surprises. In my photos, please overlook the puttied knotholes and you'll see a fastener-free surface. One caveat: the first (and maybe last) board(s) won't be this way. You can't get a good angle to install a pocket-hole screw for these, so I used counter-sunk deck screws and wood putty on top, to preserve a fastener-free look. TIPS: • An angle drill or angle attachment for a drill is super-helpful for installing those first boards or any that can't be accessed with the pocket-hole screws. • For the first several boards, I found it easier to mark first, then drill on sawhorses, replacing to install. Once I got a few feet from the house, I just drilled and screwed boards in place. • You may be able to 'correct' and straighten boards that are warped, if you use the spacer guides near your first screws, and then space while pushing in against the board as you go. •Using two drills saves much time if you are drilling and screwing as you go. NOTE: I see this is marked as a "frequently returned item." It's most useful for a handy homeowner. Commercial deck builders will either have more substantial tools, or use more efficient (but less aesthetically pleasing) methods such as pneumatic nailing. If you have the patience and can follow instructions, this is a very useful tool. In the photos, I've just finished the deck. I haven't stained it yet and don't know about the longer-term reliability of the Kreg screws, but I will update this as I see how it does over time.

Beautiful but very fussy!
This is not the quality I expected from Kreg Tools. My deck does look great but it took about 4 times longer to completed. Here are a few things that might help you. 1) Screws round very easy. For me if I kept them out of the sun they seemed to be better. 2) Just don't use the jig when installing the screw. Go nice and slow and I think you will be less frustrated and less stripped screws. I did not have a problem with the drill but the driver bit is about 1/2 as thick as the driver bit in the Pocket Jig. Which means it flexes which unseats the head and then you round off the screw. I use almost every bit of length in the Pocket Jig but on this one both the drill and bit were about 1 to 1 1/2 inches to long which also lead to stripping. I found I was not strong enough to hold down the jig and screw in the screw when working on my none dominant hand, results were better if I just worked with out the jig. The other thing that was frustrating was the collar on the bit. It would not stay in place. I tried every way to install it and it kept coming off. No problem with the drill collar. I would not buy this again and I would not recommend it.

The jig is only suitable for gaps of 5mm or greater between decking boards. If the gap is smaller the drill bit cuts into the adjacent board leaving a mark. In addition, only the Kreg screws fit into the jig meaning you have to buy their own screws that use a square shaped bit rather than a standard hex bit. I do not recommend buying this product if you want a 3mm gap between your decking boards and don't want to use the Kreg scews.
