The first thing to note here is that if you're already a battery-powered Ryobi tool owner, the Ryobi RRS1801M Reciprocating Saw represents a great deal for you, because it is supplied as body-only.
It uses any Ryobi One Plus lightweight Lithium Ion battery, so if you have these batteries you'll make a good saving against a sawzall from another manufacturer. And being battery-only, it's much lighter than many mains-powered saws.
The Ryobi RRS1801M 18V Reciprocating Saw can be used to cut metal or plastic pipes, boards, branches and other tough materials. The variable speed allows for total control no matter what the project is, and a 3100 SPM (strokes per minute) rate means you can cut metal, at a decent, steady pace.
The saw weighs 1.9kg or 4.1 pounds and measures 21 x 28.5 x 36.5 cm. A battery adds around 25% in weight.
The anti-vibration technology ensures a controlled and convenient cut each time and means you won't feel the discomfort associated with the repetitive vibration of some power tools.
The trigger safety is operable from both sides of the strong grip which users find very useful.
But perhaps the battery system is the big feature here - the RRS1801M is part of the Ryobi One Plus range - the world's largest interchangeable cordless power tool system.
The lightweight Lithium Ion batteries, mean it is always ready to use with no self-discharge and no memory effect, a long run time and improved durability. And of course battery powered technology means you're freer to work in more remote places than when your saw is mains-powered.
One user mentions that the saw is fast, powerful, and it's easy to change the blade, but they strongly recommend getting the 4.0 or 5.0 AH battery, as they say the 1.8 does not last long enough to be useful.
Another user says the tool is excellent for rougher cuts, but advises that you should buy a range of blades to broaden its use. Again - use the biggest battery you can.
Other users note that the Ryobi is much lighter than a corded saw, and that it feels solid and well-made.
