Some problems but brilliant bit of kit
Had a problem where the bars of 5 star restraining knobs did not fit into track. However, by using my feather board bolts from same track it worked perfectly (thank you other Amazon user that suggested it). Once everything in place. Off you go. Brilliant piece of kit. Very happy and easy to use.

Pricey - but I needed a treat
It's everything I expected it to be. Not sure how long the t-slot track will remain sturdy being mounted into MDF. For the price I would have expected it to have an aluminium base - but hey - I knew what I was buying. I see a question regarding will it fit on Lumberjack RS1500 - yes it will - though you need to borrow some parts off the front feather board that slot into the narrower t-track and all is then good and solid. Bit of a learning curve - of which i'm only part way through but initial cuts look promising. Deffo get an upcut spiral end bit for this - straight cut just tears everything out. So as it was a treat - I'm reasonably happy - but I could have made it myself for far less

Easy to use / set up
Great results with this jig, straight out of the box. Works really well, good easy to understand instructions. Just make sure you do not use cheap router bits.

Perfect box joints
I found this jig easy to use and my very first box joint was perfect. Only one stipulation , the manufacture should inform buyers that extended router bit may be required when using this product. Great service Amazon

Not as cosmic as Youtube tell you
This is an 'okay' product, but I suspect it's a very old model being shipped. Once set up it's fairly easy to use but the wood dust does build up in the tracks and needs constant monitoring. This is partly because my fence doesn't go back far enough and partly a design flaw.

Did not fit my T-Track, but I mounted it on a sled ...
Having tried building numerous DIY jigs from videos online I decided to treat myself and buy this item. After numerous attempts on scrap wood, it finally worked and produced a good result. My second attempt on different material involved more faffing about, but with patience, and lots of test cuts, it can produce tight joints. Had it been 20 % cheaper, I would have bought it months ago ...

Need to buy Rockler Router bits.
Great and easy, but it would be better if sold with the router bits as an extra where required.
