Not a toy. Really works
I bought this a year ago. I was skeptical about a battery operated chainsaw but after trying it I was amazed. I liked it so well I bought
One for my son and daughter. My son said that when his friends saw how good his worked, they wanted one to.

Excellent chain saw
I have owned this chain saw for over two years. It has worked flawlessly. It is a remarkably strong chain saw. I am amazed by how well it cuts. It has been used to cut down at least 200 small trees and many large limbs. It has not needed repair parts, but I know they are readily available. I have purchase extra chains, because the replacement chains are less expensive than sharpening. B&D and other brand chains are readily available at low prices.

This is one of several 40v products that I own. My only problem with any of these 40v products is that two battery units have failed (I have had at least 6 products with 40v batteries, and I bought two extra batteries, when on sale).

It would be nice if B&D added a telescoping 40v tree-limb pruning saw.

Light weight and easy to use
I find this saw to be very easy to use and maintain even in the field. The battery last for a good amount of time to get the job done. The charger does a full charge in a short amount of time. I would recommend, and have, this saw to the beginner.

I bought this saw for home use, but I needed a chainsaw when called out for trees on road at our volunteer fire department this 12 inch blade would do for most of the calls. It was used to clear roads after a hurricane small trees and branches.

Perfect sized saw for small woman
We are renting a house with a LOT of old dying pine trees interspersed with sweetgums coming up everywhere. When we moved here, English and poison ivy had almost eaten all the trees, which I'm working to eradicate. I don't have the skill or experience to handle the whopper pines, but after watching training videos on YouTube, I've been able to take down a number of the smaller pines and sweetgums myself and buck them into short lengths for use as forest garden edging and hugelkultur materials. The main thing I'm trying to do is open up the property to more sunlight and return a portion of the forested area to deciduous hardwoods; this means I have to think carefully about what I'm doing and observe the impact of taking a tree down here, a tree down there. A tree service would have charged me several thousand dollars to thin out what I have been able to do myself, me, a little old lady under five feet tall with badly arthritic hands! I love the power and control this saw gives me! Just learn the techniques and safety cautions, and regularly clean and sharpen your saw, and you'll be able to do it, too.

Better than expected
I honestly didn't think this saw was going to be nearly as useful as it is. It cuts through up to 7" Trees so far. Very easy to handle and battery lasts for a good few hours. Gotta say I'm not usually impressed, but this saw is great.

Excellent Chainsaw
Would recommend this product to any home owner that needs a chainsaw for moderate trimming maintenance around the house. The whole 40v Max System is great.

Easy To Use
Great little saw and faultless service.
I limb our trees and often get a few feet off of the ground on a sturdy ladder with a helper (wife)' The size and light weight are a good fit.
June 9, 2016
I bought this saw for my wife to use since I am handicapped and she could not handle my gas powered saw. We had some downed tree limbs and it worked great to cut them up into easy to lift pieces.

Does it come with battery?
A shopper on Mar 30, 2017
BEST ANSWER: yes it does!
Does this come with a battery charger? I would think it would but it is not mentioned in the "includes" section of the product description. If so, is it the fast charger or the slow charger? Thanks.
Ken on Aug 15, 2015
BEST ANSWER: Yes, this chainsaw includes a battery and fast charger.
Does the 8.3 weight include the battery?

New Vs. Reconditioned

What's the difference between New and Factory-Reconditioned?

Factory-Reconditioned products have been returned to the manufacturer and are restored to like-new operating condition; they go through a rigorous testing and inspection process. Plus, they offer a significant savings vs. new.
  • Reconditioned products may have minor cosmetic blemishes or scratches that do not affect item performance.
  • Reconditioned products may not come with all of the consumables the new version comes with (bits, sanding pads/papers, cases, etc.).
  • Both come with a manufacturer warranty and are covered by our Money Back Guarantee; New is 30 days, Reconditioned is 120 days.
