Really cool and useful
Good material, precise in both 3/16" and 1/4" reveal, I use it literally all the time when installing trim. It's especially great for door casing because you can fit it in the top corner behind the door on the hinge side and still make your marks accurately. In other areas you can mark easily or just stick it to the jamb and push your molding to it and drop a nail and the reveal will stay consistent. Also it's really cute and tiny and would fit in any small pocket of a toolbelt or clothes. I just recommend tying it to a string because it's so small and sometimes hard to find in the bottom of a pocket or if it falls.

Simple to use and precise.
Great tool. Simple to use. Trimming out a dozen doors and this definitely cuts down on overall time and makes a nice reveal.

Quick trim reveal tool
Handy trim tool, but you must pay attention to which side the measurement corresponds to.

Simple to use
Cool, simple little gadget that does what it says it does. Found it easy to use for getting proper measurements on door and window trim.

Read the reviews before you buy
This is a small piece of plastic that bends too much for any real repeated use. If it were tougher plastic then I would not have a problem with the price but as it is I cannot recommend this product to anyone who is a carpenter by trade. The product I received should be $1.50 on Temu. I wish I could have given this a better review but I had to be honest.

Great Little Tool
Love this tool! Simple in design and simple to use - it saved a ton of time when we replaced all of our interior doors. One improvement I’d like to see is to highlight the “1/4 inch” and “3/16 inch” lettering so we can see it at a glance. I had to shine a light on it to see. Overall, a great tool.

This product is falsely advertised. It only has 1/4 measurements. Very disappointing.
