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.

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

Works great, light and easy to use
Works great, light and easy to use. I was reluctant to buy one that only adjusts in 1/4” increments but the other ones seem clunky and will take more effort all the time just to help you on that rare occasion you actually need a different fraction. Plus you can cheat on this one by using a different size bit - using a 5/8” bit will subtract 1/8” from the diameter you select for example. Quick setup, the only thing I thought was strange is it’s calibrated for a 1/2” bit but you have to center it with a 1/4” pin. Not a big deal though.

Hubby just made a 12.5 inch 3/4 inch circle for me. It's perfect. He is going to regret buying this cause I have a list of things I want made! It arrived way ahead of schedule and he is very pleased with it.

this is the second time that I ordered and product arrived damaged. I lost a big client because of this unprofessional behavior plus un professional as well. The other one Jasper 390 product arrived damaged and in cheap condition. and those are the most expensive items in anywhere.
