Rated 3.9 out of 5 by 53 reviewers.
Rated 1.0 out of 5.0 by Would not fit. Would not fit my DW715 saw even though the product info claims it is designed for it. Had to return it. January 28, 2014
Rated 1.0 out of 5.0 by Does not work with the newest version on the DW715 Contrary to what it says on the packaging, this does not work with all DW715 miter saws. The newest version of the DW715 is series 3, and this is incompatible with it. It doesn't say that anywhere on the packaging, and you can't tell which version of the saw you have until you look at the saw itself. I contacted DeWalt and they confirmed this. They don't have a solution at this point and they say they are working on a new laser, but as of now, nothing. I'm very disappointed in both DeWalt and Home Depot for selling a product with inaccurate and misleading labeling, especially since it's been pointed out and they are aware of it. September 16, 2014
Rated 5.0 out of 5.0 by Makes life easier Helps in aligning where you are going to cut. Simple to install and adjust. May 30, 2015
Rated 5.0 out of 5.0 by Excellent The addition of this laser was great, cuts down set up times and makes cutting angles a breeze. Also installation and calibration was a cinch. February 4, 2015
Rated 1.0 out of 5.0 by Didnt work with Dewalt Miter Saw 716 I am sure this is a great product, but couldnt use it on my Dewalt Miter Saw DW716. Before you purchase this laser or the LED work light, look at the top of the yellow handle on your miter saw. If you have a small rectangular access panel with two screws that attach it to the yellow handle (should be right next to the black handle you can lift the saw with), then the laser and the worklight is compatible with your miter saw. If you do not have an access panel like mine then you are out of luck for these products. August 20, 2014
Rated 1.0 out of 5.0 by Laser easy to install, but a pain in the butt to align the laser to the saw blade I paid almost 80 bucks for this thing and it would serve me better as a paper weight. Don't bother buying this January 6, 2015
Rated 5.0 out of 5.0 by Laser Sight Works great, was easy to install. This was a great add on to my DW718 saw. It should be standard to all DeWalt Miter Saws. Set up and calibration was easy once you visualize the movements of the three adustments. Went very smooth and is very accurate. Makes work so much easier. I am extremely happy with this item. I really like that it is on alll the time not just when you start the saw like some tools, made it easy to get my work lined up first. The only issue is in bright sun, you have to shade it to see it. Even this was not really a big issue. Highly recommend to everyone as an essential piece of equipment. April 3, 2010
Rated 5.0 out of 5.0 by Should Have Bought This Years Ago! This is an adjustable laser guide that can be set to either side of your blade. While the instructions are okay and clear, I chose to set the laser up myself, having worked with lasers in industry. Attached is a picture of my DeWalt chop saw; guard retracted. Shop lights off. The laser beam is set just skimming the left surface of the bade lighting up all the teeth. Way cool. One can even check their blade runout with it! Picture doesn't capture it. Using it outside, the laser is hard to see in direct sunlight, but otherwise fine. Plan accordingly. Working after dusk can treat you to an amazing light show. Adjustments are straight forward once you get the hang of it; however, setting the cut line to the right side does max out the adjustments and might be a concern with fatter kerf blades. I treat all my power tools with the same respect as a firearm so I love the trigger lock. This is a well thought out precision (for woodworking) piece. I have used laser guides on other makes; this one is among the best. I kick myself for being "too cheap" all these years sticking to my speed square and pencil. Wish I had bought it years ago. Really speeds up one's accuracy and productivity, especially in nested cuts. December 11, 2014
