Ridgid 7 1/4 " 18 Volt Circular Saw
Only used 2 days so far, but compared to another brand, it cuts just as fast. The cutting guide for the blade lines up with the actual cut. With 4 amp hr battery it lasted about 3.5 hours cutting green oak while building a cabin. Put another battery in cut the rest of the 6 hour day.

The worst
I LOVE Rigid products, pretty much every tool I own is Rigid, so it is with great disappointment I write this review. This circular saw is crap. I have yet to get it to cut through something without it stopping, usually only 2-4" into a project. Even if I remove the blade, restart it and place it into the line I've already managed to cut it will jam if not at the same spot but maybe a half inch further in. Ihave literally only managed to get it to finish a complete pass, after many stops and starts, once. ONCE! I've tried holding it at different angles, pushing at different speed/pressure, and now on three different board thicknesses and still the same problem. This thing is garbage, especially for the price. I will now try to sell it so I can aquire a completely new saw. I'm attaching a pic my most recent attempt at cutting a 2x10 board that I tried cutting this morning, but was forced to move to my miter saw which was super fun.

Stops mid cut
This saw sporadically stops mid cut. Very annoying and near impossible to cut anything with it.

My New Go To
I have always used my battery operated systems is a backup or a small job tool and relied heavily on my corded systems. this saw what it's 18 volt system large amp hour batteries and octane configuration is a game-changer for me. I was able to complete a 10 x 20 porch without ever unloading my corded circular saw. the promo deal on the octane products where you buy the fast charger the two batteries and receive a tool is not only fair priced but a great deal. the only issue that I have had with this saw is the egress of sawdust. and this is not really even an issue after quite a few cuts due to it not clearing itself of sawdust it needs to be cleaned either with a few blows of pressurized air orabrush. the saw does come with an attachment for a Shop-Vac that you can use I have used both and found that neither mitigates this issue. all that being said I feel it is a small price to pay for the power and longevity the runtime that this provides. the material used in its manufacturing seems to me to be prograde it does not bend or twist when in use. in summary I am very pleased with this product.

I picked this up as my FREE tool when purchasing the Octane 6Ah and the 3Ah combo. I had to build an new pair of steps and some lattice frames for my front porch. This was pressure treated wood that was still very wet from the store. I was pleased with the battery life of the 6Ah and the power of the saw. I only used half of the battery for this project, including a few extra cuts to to my error.

absolutely recommend
This is a great cordless saw. Extremely powerful. Feels solid in your hands and cuts a very clean cut. I have used this for various jobs around the house, garage, and lawn. It has been durable and puts my dads craftsman and ryobi to shame and conpets with my brothers Makita and friends Milwaukee. And priced more offordable too. With either the octane battery (if you can still find them, they are amazing but sadely discontinued) or the max output you will never feel like you need a cord for more power. The dust collection works with a solid dust extractor but you’ll still get some dust being a circular saw. After three years of use this thing still feels and acts brand new. Take care of this because it is a well built little machine. Only complaint is Ridgid isnt marketing and producing the Octane line. It is great and i highly recommend it.

Might need more muscle for bigger jobs
The Ridgid 18v Octane is fine for small jobs, but if you want to cut thick lumber and cut a lot of it, it would be better to get a 36v circular saw/
