Great Tool
Great Tool for Large PVC Piping and All Demolition
Cordless Sawsall
Good Sawsall, I'm not sure if it better than the non-fuel version but having the hanger clip on it makes it more handy.

Awesome saw.
Good weight, easy to use and powerful. The mobility is great, my chorded saw is now my backup.
Just right
It's got the perfect weight and the balance is just right, so you can use one handed if the job location calls for (which is most of the time for us) Its one of the first tools I grab out of the truck
G.O.A.T
Most everybody in the construction industry compares Milwaukee to the bumblebee.. In my opinion, there’s no comparison Milwaukee by far is the superior product!
Good tool
Solid, durable. Easy to change blade, prefered by electrical contractors in our area.
Great sawzall

Great buy!
Excellent saw, the power is great! I am used to using corded tools but am impressed with the power of the new battery line of tools.
Perfect tool
This tool is perfect for anybody from casual users, to demolition use. This saw paired with a good blade can deliver all your wants and needs, look no further at the milwuakee reciprocating saw
Great tool, charger is temperamental
The M18 Fuel Sawzall is a great tool. It works very well and I am pleased with the quality and its productivity. I highly recommend the tool. With two batteries, I'm able to use it all day. The case is good quality, but seems to be larger than it needs to be, yet doesn't have a good space to store blades. The charger is very temperamental and takes a bit of fiddling when installing the battery for charging. I find that if I'm not careful to ensure that charging has started properly, I come back and find that the battery hasn't been recharged.
Wicked sweet.
Excellent piece of equipment, rugged and versatile for sure.
Great unit
I was taking down a 32yo fence using another brand sawzall which kept overheating and would quit working for a while until cooling down after removing just 2 panels. I looked up online for the best reviewed sawzall and came up with the 2821 most often. I opted for the-21 for the second battery and very pleased. This unit has more power than what I was using and doesn’t shut off from overheating.
Excellent Sawzall
Great product love the speed and the quick blade release
I will buy more Milwaukee tools
Every day on studs/ wood/ rebar and demo work love it
