15 Amp 7 1/4 IN. Circular Saw is rated 4.8 out of 5 by 100.
Rated 5 out of 5 by from Very Handy I bought this about a month ago and put it to work this weekend while building some shelves in my garage. The saw is powerful and easy to use. Plus, it has great features like the laser and rounded, hardened rubber hand grips. I cut 22 2x4's and 3 sheets of plywood and I couldn't be happier with this product! I highly recommend it for the economical DIYer.

Rated 2 out of 5 by from Design issues I manage to align the cutting blade at 90 degrees to the bottom of the plate but I had to mark it with a new reference point with a pencil because the original "0" Reference point was not at 90. See photo attached below. It was so bad that I had to flip the adjusting screw upside down in order to obtain the new zero reference because I screwed it all the way down and still couldn't get it to align to 90 degrees. Now I get the angles at the exact markings. Also, the key for the blade doesn't stay in place and it gets pushed accidentally too far towards the motor in such a way that it gets jammed between the plate and the motor and you cannot bring the angle back to "0" when making angle cuts. Resolved this issue by placing the key in the bag since I'm not going to be replacing the blade that often. Both issues are design defects that should have been reviewed during the design. Product is accurate now and works well after modification.

Rated 4 out of 5 by from Powerful saw, easy to use even for a novice I bought this for a deck project in my backyard. This is my first power saw and I am very happy with my new Ryobi tool so far. I can cut 2x lumber with such an ease. The laser alignment really helps to cut in the straight line even for a novice user like me. The reason why the stars are not 5 but 4 is the instruction manual. I really needed to understand it so that I could use the saw properly and safely, but the drawings and diagrams were consolidated at the end of the booklet and I needed to flip the pages so many times.

Rated 5 out of 5 by from Much better than my previous saw Bought this to replace the H***** F****** special that burnt up after only 2 months of owning/using it. I've had this Ryobi saw for a while now and absolutely no disappointments with it yet. Very happy with it.

Rated 4 out of 5 by from Perfect for DIYer Needed to replace old saw with warped baseplate. Couldn't beat the added value that it came with an edge guide, although it has a bit of play before you tighten it down, so you need to double check squareness. I don't really use the laser guide, so I can't speak to that. Plenty of power for what I do (mostly yellow pine grade2, both new and weathered). Power cord is perfect length. When cutting sheet material, if the dust port is ejecting onto the sheet, the sawdust will get blown into your face ... I feel this is true for all circular saws though.

Rated 5 out of 5 by from One of my favorite Ryobi tools! Bought this about 2 months ago and have given it a VERY VIGOROUS test run. I can honestly say, this saw is incredible! Has no issues with 3/4” ply, walnut, oak, pine...you name it! The laser definitely helps make straight accurate cuts without a guide. The guide that it comes with is more than enough for my needs. Directs sawdust away from you so you don’t come out looking like a muddy snowman. Highly recommend this saw for the hobbyist and the professional. More than enough power and has the Ryobi toughness you come to expect! Get one today!

Rated 5 out of 5 by from My first circular saw has been FANTASTIC Love this thing. I'm a DIY guy that does small, easy projects at home. This is my first circular saw I've ever owned. Bought it instead of a miter saw, and have used it to build my own floating shelving for my garage. It works well and has been a great intro to woodworking tools for me. I liked it enough to where I've spent another $400+ on Ryobi ONE+ tools. The rest of my items are all wireless: brad nailer, drill, driver, sander, portable light, and a few other items. I'm a big fan. Great mix of price and functionality.
