Powerful saw
Had to rip several 2x8x12 treated (these were very heavy and still wet) boards this past weekend to finish a project. Started with a German battery powered track saw (you know which brand I'm talking about "Green" with systainer carrier) anyway this saw bogged down within inches of starting. Gave up with it (yes the batteries were charged) and got the cordless Worm drive by Skilsaw out and man this saw cut through the board like a hot knife in butter. It cut them as fast as I could push it through. Highly recommend this saw. Can't wait until the bigger cordless brother comes out later this year. Thanks Skilsaw for the awesome saw!!

I love it. It's stout, smooth and powerful. This is a well balanced saw and cuts like my corded 77. For normal, non-production use, the battery lasts me all day, just like they say.

I'm glad I bought it.

I reach for this saw a lot. People are talking about the weight and size of the battery but I honestly don’t notice it because it’s so well balanced. I recently ripped 8/4 black walnut with it kind of as a joke to see what it could do and it did better than anything else I have including my 10 1/4. Comes with a good blade too. I highly recommend this saw. Don’t listen to the haters.

First cordless tool I buy.
I just bought this saw as a Christmas gift for my father. I figured it would be a good time to get him to eventually go fully cordless with tools.

I cannot believe the kind of torque these gigantic batteries can deliver. No matter how hard I push, this cordless saw just eats up the wood as if corded. The build feels solid, but would have liked for the handle to be made of metal like the rest of the saw. The saw weight is well balanced w/ huge battery inserted.

I did not give 5 stars because it's only backed by a 1 yr. warranty. There's no other tools I can use these battery packs with, and at $250/battery that's steep. I can't believe the cost of the actual tool and battery are about the same.

I'll give 4 stars if the saw holds up to the quality the brand is known for.

5 stars if they back with a better warranty, and expanded product line w/ the same batteries.

The tool needs to be time tested.

Great Saw
I’ve almost had mine for a month now and love most things about it. Saw is excellent quality as you’d expect from Skil. The battery on the other hand leaves a lot to be desired. That’s the ONLY reason I don’t give it 5stars. They claim to last all day, mine is dead before lunch. I hope they address this. And at $229+ per battery, I’d have to have 3 to make a full day without waiting on charging. I hope Skil reads this and messages me and we can come up with something. I’m a long-standing Skil Customer and currently have 8 Mag77’s, 2 Bigfoots, and 6 Hd77’s in my Arsenal.
