Rated 4.6 out of 5 by 30 reviewers.
Rated 5 out of 5 by Awesome saw! I purchased this saw to re-trim our our home. It handled it all with ease and has since proved invaluable during countless other construction projects. . I find the laser difficult to aim but have no trouble lining up the cuts manually. I am not really sure the laser is all that useful for me anyway. This thing is heavy. Buy the cart and you will be much more likely to use this saw. Also, a quality blade is as important as anything else in a saw like this. May 20, 2015
Rated 5 out of 5 by Best compound miter saw I have ever owned. This compound miter saw has the brute force of a chain saw with the finess of a scroll saw. Everything I have thrown at it it cuts with absolute ease and control, from 6 x 6 timbers to 1/4 molding. The laser is accurate and the blade brake if very fast. The work clamp is especially handy when working solo. This beast is definitely worth having in your work shop. The life time warranty is just icing on the cake. December 12, 2014
Rated 5 out of 5 by Best chopsaw I've used so far I have been around many different job sites and have seen all kinds of differnt chopsaws. After using many different brands and getting input from other contractors, the only saws I will put on my job sites are ridgid!! I have never had any problems with any of the saws. No down which is huge! Do time equals money. November 28, 2014
Rated 5 out of 5 by This product is very durable. I have used this saw on many jobs from cutting rough lumber to expensive hardwood trim. It has worked exceptionally every time. November 26, 2014
Rated 5 out of 5 by Great addition to you tool collection This is a great saw, well worth the money and the amazing customer service. easy to use and adjust. I wish the had a package deal with the work bench like the other competitors do. thanks rigid November 26, 2014
Rated 4 out of 5 by Great Saw! Excellent saw for the money, cuts true just a little heavy to move November 25, 2014
Rated 4 out of 5 by This saw does the work for you With this saw (and stand) you can look like a professional. The only reason for 4stars and not 5stars is the laser is WORTHLESS. as long as you measure twice and cut once you will be very happy with the outcome. November 25, 2014
Rated 5 out of 5 by This Saw is great to use i had other Miter Saws from Canadian Tire and Etc, ...... but i love my Ridgid Miter Saw ....Lots of Power and Easy to set up with the Ridgit Stand i bought to at the same time ....like the fact it has a Life Time Warranty on it .........
