Sturdy, reliable, accurate.
I want to preface this review by saying that if you don't take proper care of your tools, of course they are going to let you down. You don't expect to get 100,000 miles out of your car if you never change the oil, right? Having owned this saw for nearly a year, I can say it has been an essential part of my day-to-day. The laser is deadly accurate, the base is extremely sturdy, and the motor delivers enough power to work it's way through anything. The bevel and miter adjustments still glide as smoothly as they did the day I bought it, and the positive stops for common cuts really come in handy. One of my favorite features is the mechanism that locks the blade down when you store it because it also serves as a stop for making repetitive cuts at the same depth. This is especially useful for lap joints that I go in and clean up with a chisel because it saves me from having to set up a guide for my circular saw or busting out my table saw. There are only two things I find lacking: 1) the dust collection, and 2) the clamp. The dust collection doesn't readily receive PVC fittings to hook up to a vacuum, which is a bit of an annoyance, but I do believe this is something RIDGID has heard multiple times and is working on. The clamp is a bit weak, and when you twist it to put extra pressure on the material it sometimes bows. This doesn't cause any defective cuts as far as I've seen, but it is a minor concern. Overall, the value and quality are excellent. Again, you have to keep proper care of your tools, and if you do, you'll get many, many years worth of work out of this saw. It's fully capable of tackling a wide array of jobs and does so with ease.

Rigid 12" sliding compound miter saw.
I purchased this a few weeks ago when I had a break in the snowstorms,I plow and sand for a municipality. I have read reviews for every saw out there. I have talked to contractors whom i've known for years. They were all over the place with their opinions. Home Depot reviews helped me make an informed decision and I appreciate that. I also could not find the write a review section when I was looking at it all along. I wrote Home Depot Customer Servive and they e- mailed me ,gave me info they are on the job!!! Back to the saw,which is perfect. I also bought the Rigid MSUV stand. The owners manual says that the saw is set from the factory. Upon a few test cuts, it's perfect. I read the manual from beginning to end and every adjustment you would need is explained very simply. The MSUV stand is equally ,incredibly heavy duty ,solid build and heavy.The Home Depot employee who helped me was great. I have asked him for help over the last few years and he's great. Overall I enjoyed a good experience Thank You ,Home Depot, Mr. Lauren, Hampden,Ma

    exellent tool very reliable
    We recently replace 10 windows in our house. I have done trim work with marginal results. They say it is a poor carpenter that blames his tools But I will give credit to my Ridgid miter saw for excellent result.

      Poor dust collection and blade guard.
      I had owned this saw for about half a year but only used it for a few month before the blade guard was not moving up and down. I bought this before another one of my major projects because of the combo deal but wish I wouldnt have bought it so far in advanced so I could have returned it. Do a quick search on Google and you can see that this is a problem with this particular model. The only reason I bought this is that my Dewalt was stolen and I read good reviews on this particular saw. I purchased when the stand and saw were bundled which was a great value. The saw has more than enough power and the sliding rails are nice and strong. Im not 100% sure but I believe that the fence is higher than my old dewalt which is nice for crown. However the biggest down falls are that it is heavy ( or at least in relation to my old dewalt) the dust collection system is awe full, and the particular problem with the blade guard has put my saw out of commission for 3 weeks. Its nice to have the warranty, however I was told it would be fixed in a week from my local Home Depot, but I am still waiting on it. Overall the only thing that would make me happy with this saw would be a refund or trade it back in because I cant wait a month at a time for it to get fixed.

        Great Saw
        I am very happy with the performace of this saw so far. It will do any cut I need and the laser is also a handy feature. I bought it with the stand and it is very handy, much easier than lugging around my old one and trying to use my truck tailgate or building a stand for it. The saw itself is bulky but what do you expect from one this size? The saw makes great cuts and I am really excited about the lifetime warranty. Ridgid is now my tool brand of choice.

        Great Saw
        Great saw upgraded from 10" to the 12". Sliding feature is smooth make sure to keep slide clean of saw dust. Makes it easier to use. The pre-settings for crown molding makes it easy peasy to use. Make sure to follow the instructions in the manual if you don't know how to square a saw. Other wise your saw may not cut square. Best one out there, I have used other brands. This one beats them, the only thing is the weight. But they all weigh a lot, I would suggest buying the suv saw stand. It makes it silky smooth to use. Some of the other reviews have complained about size and the volume of the saw. Power tools are loud, that is why you should wear hearing protection at all times.

        The Rigid 15-AMP 12 IN. COMPOUND MITER SAW WITH LASER exceeds the already high standard I set from using my other Rigid tools. Right out of the box my saw cut a perfect 90. I still have yet to try the laser as this is a new feature for me since lasers on all my past miter saws were worthless, but this seems to break that trend. IF YOU ARE CONSIDERING PURCHASING THE AC9945 MITER SAW UTILITY VEHICLE, MY ADVICE IS DO IT! The Utility vehicle operates so smoothly and makes carrying weight of any miter saw (universally fits most saws) that is worthwhile effortless. It is amazing how well balanced the utility cart is. I recently got to see one of the 15-AMP 12 IN. COMPOUND MITER SAW WITH LASER in "well used" condition on a job site. I asked what they thought about the saw it got rave reviews. Those are my thoughts and experiences.

          Overtime the blade became less "true" with the slider. Look on Amazon you will notice others are having the same problem. Rigid will not stand by the life time warranty with this issue, claiming it is not a product defect.
