12 in. Sliding Compound Miter saw with LED is rated 4.6 out of 5 by 76.
Rated 5 out of 5 by from Excellent tool! I make things out of wood for a living, and I had been wanting to upgrade for a long time. I have been very pleased with the prices and the quality of the Ryobi One+ line and decided to give this 12” Sliding miter saw a try. I could not be more pleased with my purchase. The saw works perfectly, the blade was perfectly squared out of the box, and the LED cut predictor is a very helpful addition. I really like that it had a depth stop on the saw so I can make cross cuts without cutting through the workpiece if desired. This is a high quality, smooth working saw at an affordable price. If you are in the market for a heavy duty miter saw, I would recommend buying this one.

Rated 4 out of 5 by from Great quality for the price I bought this about a month ago and it has been put through the paces for sure. For the amount we paid for it, it has performed well above expected. Our only issue with it is that the led light is not a laser and is less accurate. The light just shines over the blade and the distance from the material surface changes the width of the shadow created. We would prefer a laser, since it maintains a consistent reference line and easily repeatable cuts on a job site. The learning curve to get it within our required 1/32 tolerance takes time, but not impossible. Overall happy with the saw given the low price point.

Rated 5 out of 5 by from A Great and Dependable Woodworking Companion! It's my first time owning and using a miter saw and I can say that this Ryobi Miter saw delivers and surpassed my expectation as a person newly engaging in weekend woodworking hobby. It helped me produced accurate and clean cut lumber pieces including those that required angle cuts. It helped me rebuild my water heater shade quickly and efficiently. The result was amazing. I love this miter saw. I highly recommend this to everyone. Because I'm so impressed about this product, I am now a proud owner of other great Ryobi tools including Impact Driver, Drill/Driver, Circular Saw, Reciprocating saw, Multitools, LED light, Hand Planer, grass trimmer and blower.

Rated 5 out of 5 by from Great saw with plenty of power. The led light on this saw is bright. One feature I really like is that the light cast a shadow exactly where the blade is going to cut. In my opinion this is much better than a laser which are typically inaccurate

Rated 4 out of 5 by from Good saw Bought this roughly 6months ago and very happy with it. I was skeptical with a ryobi saw but ryobi delivered. Had very small adjustments for true 90 and 45 but will have that with any saw. I’m a weekend warrior and more than enough saw for my needs.

Rated 5 out of 5 by from Love all my Ryobi Tools Bought this to add to my Ryobi collection of tools. Easy to use and works better than competitors. I also suggest getting the stand for it if you do not have a work space for it!
