Kreg KJDECKSYS20 Deck Jig Review: Achieve a Flawless, Fastener-Free Deck\n\nTired of unsightly screw holes and splinters ruining the beauty of your deck? The Kreg KJDECKSYS20 Deck Jig offers a solution by enabling you to install deck boards with hidden fasteners, creating a smooth, professional-looking finish. This jig is designed to simplify the process of creating perfectly spaced and angled screw holes, making deck building more efficient and enjoyable. If you're a homeowner looking to upgrade your outdoor space or a contractor aiming for higher quality deck installations, this jig could be a valuable addition to your toolkit.\n\nThe Kreg Deck Jig works by guiding your drill at the correct angle to create pocket holes along the edges of your deck boards. These pocket holes allow you to screw the boards down from the side, concealing the fasteners from view. The result is a clean, fastener-free surface that's both aesthetically pleasing and safer to walk on. Compared to traditional top-down fastening methods, this system significantly reduces the risk of splitting the wood and creates a more durable, longer-lasting deck.\n\nWhether you're a seasoned DIYer or relatively new to deck construction, the Kreg KJDECKSYS20 Deck Jig promises to streamline your workflow and deliver professional results. But is it truly worth the investment? Let's dive deeper into its features, advantages, and disadvantages to help you decide if this jig is right for your next decking project.\n\n## Key Features of the Kreg KJDECKSYS20 Deck Jig\n\nHere are some of the key features and specifications of the Kreg Deck Jig:\n\n Hidden Fastener System: Creates a fastener-free deck surface for a cleaner, more professional look.\n Hardened Steel Drill Guides: Ensure precise and consistent hole placement, reducing the risk of errors.\n Spacing Shims: Built-in spacing shims automatically provide consistent 1/4-inch spacing between deck boards.\n Drywall Stop: Helps to quickly and accurately repeat the pocket hole process for a perfectly aligned deck. \n Durable Construction: Built to withstand the rigors of jobsite use, ensuring long-lasting performance.\n\n## Pros: Advantages of the Kreg KJDECKSYS20 Deck Jig\n\nThe Kreg Deck Jig offers several benefits that make it a compelling choice for deck builders:\n\n Professional Finish: Creates a smooth, fastener-free deck surface that enhances the overall aesthetic appeal of your outdoor space.\n Increased Efficiency: Streamlines the deck building process, allowing you to install boards faster and with greater accuracy.\n Improved Durability: Reduces the risk of splitting the wood, resulting in a stronger and more durable deck that will last for years to come. Hidden fasteners also prevent water intrusion from the top, reducing rot.\n User-Friendly Design: The jig is easy to use, even for beginners, making it a great option for DIYers of all skill levels. Simple setup and operation mean you spend less time figuring out the tool and more time building.\n\n## Cons: Disadvantages of the Kreg KJDECKSYS20 Deck Jig\n\nDespite its many advantages, the Kreg Deck Jig does have a few drawbacks to consider:\n\n Requires Specialized Screws: The jig requires the use of Kreg Deck Screws, which may be more expensive and harder to find than standard deck screws. This adds to the overall cost of the project.\n Pocket Holes are Visible from Below: While the fasteners are hidden from above, the pocket holes are visible from underneath the deck. This may not be an issue for some, but it's something to consider if you're concerned about the aesthetics of the underside of your deck. You might need to take extra steps to conceal them if necessary.\n\n## Who Should Buy the Kreg KJDECKSYS20 Deck Jig?\n\nThe Kreg Deck Jig is an ideal tool for a variety of users, including:\n\n Homeowners: If you're a homeowner looking to build or renovate your deck and want a professional-looking finish, the Kreg Deck Jig is a great investment. It simplifies the process and helps you achieve results that are comparable to those of professional deck builders. The satisfaction of creating a beautiful, durable deck yourself is a huge bonus.\n\n DIY Enthusiasts: If you enjoy DIY projects and want to tackle deck building, this jig makes the job significantly easier and more accurate. The learning curve is minimal, and the results are impressive, making it a worthwhile addition to your tool collection.\n\n Professional Contractors: While professional contractors may already have experience with deck building, the Kreg Deck Jig can still be a valuable tool for increasing efficiency and delivering consistent results. It can help you save time and reduce errors, ultimately improving your bottom line. Offering hidden fastener decks can also be a great selling point for higher-end projects.\n\nFor those prioritizing speed and cost savings above all else, traditional top-down screw methods might be preferable. However, for those seeking a premium look and enhanced durability, the Kreg Deck Jig offers a compelling solution. Consider your priorities and budget before making a decision.\n\n## Conclusion: Price, Performance, and Recommendation\n\nAt a price point of $39.33, the Kreg KJDECKSYS20 Deck Jig offers excellent value for the performance it delivers. While it does require specialized screws, the resulting fastener-free deck surface and increased durability are well worth the investment. Compared to similar hidden fastener systems, like the Ipe Clip system (which is often used with hardwood decking), the Kreg jig offers a more affordable and accessible option for a wider range of users and decking materials.\n\nIf you're looking to build a deck that stands out from the rest, the Kreg KJDECKSYS20 Deck Jig is an excellent choice. It simplifies the process of creating a beautiful, durable, and professional-looking deck, making it a must-have tool for both DIYers and professional contractors.

I switched to VCF because hormonal BC was giving me crazy migraines. It took a bit of practice to get the placement right (it can stick to your finger if you aren't quick), but once it's in, you can't feel it at all. It’s affordable and I like that I only use it when I actually need it instead of taking a pill every single day. Just make sure you read the instructions about the wait time.

It’s okay, but some of the movies are kinda obscure. I wish the scratch material was a bit easier to get off without worrying about ripping the paper underneath. Decent value though.
