Rated 4.4 out of 5 by 116 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 3.0 out of 5.0 by This is a light duty saw, but works ok for 2x4 or smaller If you don't need to cut anything bigger than a 2x4, and you are not making a lot of cuts, this isn't too bad of a saw. If find that it cuts pretty slowly, and if you are expecting 110v performance, you will be disappointed. It has much going for it, like size, weight, price, and being cordless. I use it out in the wood, which makes it nice to have, but it would be much better if it was faster and could cut larger lumber. My main issue with this device is that it binds up with out much pressure, shutting the saw off. September 18, 2015
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 cordless saw, excellent value This is such a great little tool. If you already own this line of tools/batteries then you'd be silly not to add this incredibly useful bench-top and portable tool to your shop, garage or truck. October 6, 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 5.0 out of 5.0 by great product like most of the rybi one+ tools made cutting my trim work a lot easier then other saws did. November 15, 2015
