A solid and easy to use product.
Worked like a charm. It is extremely durable and easy to use. I bought this item because the one I wanted wasn’t available. I don’t regret getting it.

very nice tool
likes, all aluminum construction, seems very accurate and uses more sturdy 1/4 inch shelf pins instead of the 5mm ones
comes with 2 bits which is a huge plus the competition makes you buy the 1/4 drill and only is set up for 5mm to start.
this jig will work along side, for now, my other jig
dislike is the fact it only has 1/4 pin capability not a deal killer in any way, and it has "pins" to support the jig on the edge again this is both an advantage and disadvantage as you can change the depth of where the pins are located BUT if you are making something smaller the jig may not calibrate consistently.
on another positive you can replace the bits easily and commonly as they are not proprietary and simply standard 1/4 inch bits
this will be a fine addition to my other goingmake tools and future ones

Sturdy and well made
I have yet to use this jig, but on initial inspection it is well made and no doubt will withstand a lot of use. The machining of the threads was rough on the one I received, but after screwing in the guides a couple times the operation became smoother. Probably lack of cleanup after anodizing left in the threads. Other than that it looks like it will be useful and longer lasting than many of the plastic jigs out there.

Easy to use
I built a bookshelf for my grandson and wanted adjustable shelves. This jig did the trick. Very easy to use, and a lot of adjustability. I have other tools by goingmake and they all are well made and affordable.
