One of the best sawzall on the market
Best sawzall I have ever had, great power. I have been using it for about a year now and the only problem I have experienced with it lately is that, it’s a bit difficult to change the blade sometimes.
I still believe it’s one of the best sawzall on the market right now if not the best.

Great sawzaw with a very convenient handle. The power stays strong as long as the battery Is charged id recomend a high output battery for it gives it that extra power to cut metals and mow through nails I'm happy I bought this!!!

it is worth the up grade from the older version.
One of my go to tools for every teardown project I have. Runs hard, but still eats out juice considerably.

Is this a reconditioned saw??
Levi F on Aug 24, 2017
BEST ANSWER: No it was brand new. You can tell by the model # 2721-20, if it was reconditioned the last two digits would be 80 = 2721-80.
Does this come with a bag?
A shopper on Dec 3, 2019
BEST ANSWER: No bag is listed in the includes section.
Which m18 battery. Xc5.0 xc6.0 xd9.0??
Joe S on Nov 18, 2018
BEST ANSWER: You can use all three, the battery will only have to be in the M18 family. You can use any amp hour battery for this model.
