Love these jigs
I love this thing. Accurately cutting circles can be a pain, but with this jig, it is simple and very accurate. I bought the smaller jig from this company and it worked so well, so when I needed to make a larger cut circle than it could handle it was a no-brainer. I needed an exact 30-inch diameter cut and using this made it so easy and nailed the cut accurately the first time. As much as lumber costs right now, not having to re-cut something is so valuable. I know there are other jigs like this out there - they may work well too - but I know this one works like a charm.

Excellent! Does more than round table tops!
This is the simplest and best router jig I’d ever used! It is very precise and has a very tight fit! I used it with my 15+ years old Bosch EV series router and both of them worked magic for me! Highly recommended!About the photos; the images show the base from which three lamps will be hung in due time.

Works Great, Well Made and Reliably Sturdy
Arrived without incident. Just cut my first circles (47.5”) with this jig. Fit my Skil Plunge Router without issue. Look forward to using this jig a long long time. Makes it easy to gently pull the router around the circle without issue. I hung my power cord and vacuum hose from a cable tie connected to my garage door (in the up position) above my portable bench, to make it easy to continuously cut without being distracted by either of those items. This jig is well worth the money in the quality of the cuts you make, and the time you save, vice using a jig saw free hand.

Incredibly helpful!
The Jasper 300 XLC Circle Cutter Router Jig allowed me to create the perfect top to this arched door. Started with three doweled and glued boards, then routed with a 1/2" diameter upcut spiral bit. After watching the how-to video, reading instructions, and testing a couple times, the jig worked great! VAST improvement over my jigsaw cut first attempt at an arched door.

Calibrated for 1/2” bits?
Don’t get me wrong, this thing makes cutting circles, incredibly easy. However, I was definitely bummed out to find that the 300 Pro is calibrated for a half inch bit, as I am using a quarter inch. So now I have to figure out which hole to use because the “correct” hole is no longer correct.. First world problems so they still get five stars

Markings will ruboff over time
This device works very well but the markings are printed on the underside of the guide and rubs against the the wood. Over time the markings start to rub off. This is why I gave it 4 stars
