Worth the money although could be cheaper for a piece of plastic.
As a general contractor and finish carpenter I was at first skeptical about the tool after using it was a good investment.

Amazing tool!
This simple little tool has made the molding a lot easier than expected. It made the bullnose corners easy for an amateur such as myself. I would highly recommend this to anybody doing trim with bullnose corners.

Super useful tool that helped manage those outside corners!
Great product and reasonably priced. I can not even imagine doing trim work anymore without this handy tool. Has a permanent spot in my toolbag now.

Joseph F on Jul 15, 2018
Replacing 360' of 3.25" base molding with 5.25". All outside corners are 3/4" bullnose. The old molding had bullnose corner pieces but I will be making my own three piece corners. This jig should make that job easier.

Doing trim on round corners is a pain. This is close to a tool I designed to help the process but looks more refined. Anything that helps the accuracy of the installation process is great!

Have rounded corners and am doing trim
Ronald G on Aug 26, 2017
I have a bunch of base molding to replace and I was hoping to make the round corners a bit easier. I had decent luck with the method I used by taking a pattern from the old molding I took off, but 2 joints instead of 3 would be nice. I'm still not sure how nice a job it will do on the round corners...

Using the bullnose trim gauge...I line everything up and fits great. When I nail the midle bullnose piece, it shifts and is a little off. Happened 5 out of 5 times. What am I doing wrong?
Bullnose 5150 on Feb 24, 2017
BEST ANSWER: Just nail the side pieces and glue the center piece to the sides. Nailing into curved metal can cause the small trim to shift.
Can I use this tool to cut out the middle piece?
Bruce on Aug 31, 2017
BEST ANSWER: No, you can't. However, the instructions are very clear on how the piece needs to be cut.
will this tool help with 22.5 degree inside and outside pieces?
rob w on Dec 26, 2017
BEST ANSWER: Yes. This tool makes bullnose corners easy. Just follow the simple instructions and you can’t go wrong.
