  • Saw
I restored furniture. This is the first saw I have used and it's easy to use. When I need to cut something, I don't ask my husband anymore. And I love that!

  • Great price and works perfect.
Style: 7-1/4 Inch
It took little time to put together and before I knew it, I was getting to work and it went through a whole stack of 2x6s as if they were butter. Great little saw.

  • Enough blade to cut a 2x4.
Used it on a project with a lot of 5/8" plywood. Worked great. Well balanced. Very easy to maneuver. Really should be called a compact worm drive. Feels sturdy. My tenant is a carpenter. He used it once and bought one for himself. laser is worthless in sunlight.

  • Perfect Power Saw
I had been looking for a lightweight power saw to cut wood into pieces to make flower presses. I did not want a huge circular power saw, and when I saw this one I thought it would work out. And work it does! It is not heavy, it is easy to use and the saw has a light for guiding the lines one wants to cut. I find it easy to maneuver, especially easier than something like a bulky skill saw. I am a female and while I am strong, I really wanted something I could easily pick up and use without giving much thought to whether or not it would be safe. This saw is easy and feels safe, and I am not intimidated by the power. The saw came with an extra blade, has a variety of settings and is a must have for anyone looking for a power saw that offers ease of use. ... show more

  • This circular saw is a piece of crap
Style: 20V 4-1/2 Inch
I bought this power smart circular saw 12/6/22 I had it still boxed up until I got ready to use it on 4/1/23 the blade turned over once and it never turned again, you can hear the motor running but the blade won’t turn and the brake that stops the blade from turning when changing the blades that do not work. I’ve tried calling customer service for almost 2 weeks I have called and been on hold for over an hour at times but the last time was 4/11/23 I waited for an hour and twenty-five minutes before I hung up the phone this is the worst customer service I have ever experienced in my life. I guess I can see now no wonder the product I bought the power smart mini circular saw didn’t work it’s just like the customer service just plain awful and the worst of any product made that don’t work when unboxed I did research on this product before I purchased it and thought it was the best but evidently I didn’t do enough research because It turned out to be the worse I should not have purchased this product because I did not get to use it once the mini saw never worked. I am very disappointed in this product. Once I was contacted by customer service we emailed for about 2 weeks they gave me the run around back and forth then said for me to take it apart I responded I will not do that it’s still under warranty then all contact was broken off I didn’t here from them again so I just purchased me a Dremel saw and it works great best purchase I ever made. ... show more

  • Really liking this tool
So far I’m really enjoying this tool. I have been cutting 2 x 6 and 2 x 8s with it, and it rips through them pretty fast. I would say it’s about as fast as my hitachi 10” chop saw (although my chop saw blade is a Diablo 70 tooth blade, but it’s not brand new). It definitely has enough power, and it’s my go to right now over my Makita circular saw. It’s so much lighter and so I’m liking it. Very satisfied at this point. Let’s hope it holds up. ... show more

  • Well designed with one minor flaw
Style: 20V 4-1/2 Inch
Overall the saw has sufficient power and battery life. It is robustly constructed. The only thing to watch out for is that the drive gear in the last stage of the gear box transmits torque through a shallow pin or ball set into the shaft and a slot in the gear. This works fine for most use cases, but if you are cutting pavers and hit a stone in the aggregate, the energy of the sudden stop is sufficient to break that pin/ball. I suspect the same might happen if you hit a nail in a piece of wood. Up side the rest of the saw was protected from the sudden stop. Down side its broken till you take it apart and replace the pin. I never found the original, it might be stuck in the grease under one of the reduction gears. Other things to know: motor is commutated and air cooled, so if you are in a masonry trade that might limit the motor life. I don't think the brushes are replaceable. Repair tips: - if the vacuum attachment is not working look in the attachment hole in the guard, there might be flashing from the injection molding blocking the port, give it a light tap with a screwdriver and it will clear. (this might be intentional for people who don't wan tot use the attachment... have to find the manual again to be sure) - if your trigger is binding (only happened to me after taking it apart and putting it back together) back-out the screw nearest to the trigger just a bit, that will fix it. - pin is ~3mm (just under 1/8 inch) in diameter - closes I could find was 1/8 inch and had to sand it down a tad. I happy with it, but then I'm comfortable taking it apart. I figure the average user is not going to be happy doing that, hence the 3 stars. ... show more
