Rated 4.4 out of 5 by 100 reviewers.
Rated 5.0 out of 5.0 by Time Saver. This is a great product, accepts the old type batteries, it's easy to carry anywhere your work takes you, easy to set up and a time saver. I put up window trim in a heartbeat along with the Ryobi nail gun. I'm cutting tongue and groove 3 1/2 inch pine boards at 30 and 36 degrees to perfection with this saw. It stops within seconds which is saving me time compared to my 10 inch table saw in the basement, safety guards are great and the laser is a nice touch. I had to call my son in the US who ordered this and sent it to me within 2 weeks, I tried to order it online through the Canadian website but it was on backorder with no date and would not allow me to order it even though you could only order online for this product. I hope HomeDepot works out there differences with the supplier and gets this available for all of Canadians, you are missing out on a great sales opportunity. I'm a Ryobi product fan and look forward to more innovation from them. The greatest selling point is that you can use any of their batteries on any of their cordless products. September 25, 2014
Rated 5.0 out of 5.0 by Great addition to Ryobi tools. Works as advertised. Perfect for small DYI projects around the home. Used right out of the box did not have to square it up. Now all I need is a stand. December 2, 2013
Rated 5.0 out of 5.0 by Great for cutting meters. Especially if you have never done this. I purchased this model so I did not have to worry about cords and it uses the same batteries as all the other tools I purchased. For some one that never used a table saw this has been very easy and using suggestions on line I was able to make excellent cuts and the job looks great. January 17, 2015
Rated 5.0 out of 5.0 by Great Purchase After 10 years using a hand powered miter saw I finally decided to go with the Ryobi 18v Compound miter saw. I make quite a few things out of Oak 2 and 3 inch boards. Using my hand miter saw, a cut that takes minutes now is finished in a few seconds. With a Freud 60 tooth finish blade this saw makes crosscuts so clean that very little sanding is needed. I would recommend a Lithium Ion battery. My retirement projects are so much more fun now since I can see results a whole lot faster. April 29, 2015
Rated 3.0 out of 5.0 by Good for small jobs Not as powerful as I had hoped or needed. Struggles to get through a 2x4 escpecially at an angle. Good for trim and other small lumber material but not strong enough for framing. May 26, 2015
Rated 4.0 out of 5.0 by I like this saw for what it was designed for If you are going to be cutting some 2x6's, 4x4's or even 2x4's on a regular basis this saw is not for you. This saw is for small jobs like trimming out windows, framing a small closet and other odd jobs like cutting aluminum (use a 140 tooth blade) for replacement window screens. For that it is perfect. It is light, easy to pack around and best of all it doesn't need any cord to make it run. I did a small job the other day and cut about 20 2x4's, and one 2x6 and then cut a bunch of trim to add on a closet in a basement bedroom. It did all of that on one battery. In fact I built the whole closet without a power cord. Even the portable light was batter powered. For small quick jobs this is the saw to use. June 19, 2015
Rated 5.0 out of 5.0 by pleasantly surprised I love this saw. As a general contractor I have almost always carried a miter saw with me. The problem with my other saws is that take up a lot of space in my van and it was a pain to look for power when if I only needed to make a few cuts. I bought the 12 tool combo several months ago and I'm very pleased. I've used this saw to cut and install baseboard, casing, crown moulding, 2x4, etc. this saw obviously won't cut 45' on 6" crown moulding but it works for about 95% of what I need it to on a daily basis. With the 4ahr battery I can cut all day or even several days without charging July 17, 2014
Rated 1.0 out of 5.0 by Stopped Working I should have waited before leaving that 5 star review -my Ryobi miter saw is now DEAD. It quit working while I was trimming some 1x3s, so it definitely wasn't overloaded. As I previously wrote, it seemed like a power hog, so I purchased the hi - capacity lithium battery, thinking that might help. No good - the battery indicator showed it still had 3/4 of its charge, and the saw wouldn't power up. The trigger button wouldn't engage. I tried switching batteries (I tried 6 - I can be pretty stubborn), but nothing would work. I think perhaps a saw uses too much power to be cordless. I'll be taking it back to Home Depot today and buying and buying a REAL miter saw. May 25, 2015
