Brush cutting
I bought this String Trimmer in combination with a Ryobi Expand-It Brush Cutter Attachment to clear 5 acres of dense and thick brushes.
It works like a charm!
The combo can cut through brushes easily up to 1 inch thick branches. It can cut thicker also, but become more of a skill and harder on the body.
The 4Ah lasts about an hour on average when brush stems are not too thick. Usage time goes down to 30 minutes or so when stems are thick and dense and if the machine has to work harder to get through it all.
I've cleared about 1 acre so far and have 4 more to do. There's no obvious wear or tear yet and I feel confident that this combo will be able to clear all 5 acres.

Outstanding unit
I recently purchased the 14" 40 Volt cordless string trimmer and I love it. The battery last much longer than I expected. It doesn't get hot like my Gas trimmer did, the battery recharges quickly and last a long time. The variable two speeds make it very versatile. All my accessory's from my gas trimmer work great on this unit. I am extremely well satisfied.

I bought the trimmer ovber a year ago and i am glad I did. this is the seconjd season that I've used it and find it as a well balanced piece of equipment. When I bought it the main thing that bothered me was how long the battery would actually last during use and how long it would take to recharge. As it turned out I was delighted by the results. I always finished the project before it needed charging and when I did it was done before my cleanup. All in all it was the best purchase I've made in years. PS It was paid for when I sold my gas powered trimmer.

Love this trimmer!!
I have had this trimmer for a year and am thrilled with it. I have a large field area that was left unmowed for years. There were layers and layers of tall thatched grass that had to be removed. This area is at the bottom of a hill, so getting equipment down there is troublesome. I spent all of last summer clearing that field with this trimmer...and lots of raking. I am happy to say the trimmer gets a lot of use and is still going strong. The battery is interchangeable with the ones for my mower so I can extend the run time. I was tempted to go with the 60V, but thought it might be too heavy. I believe I was right. This one is perfect, and I can now mow the field.

Great trimmer!
I switched all of my lawn equipment from gas to battery and I think the piece of battery equipment that was the closest to a gas counterpart was this string trimmer. You're not going to bush hog 3 foot tall grass in a one acre field with this trimmer, but thats not what its intended for. It has plenty of power for weekly yard duty like edging the sidewalk and driveway and trimming up the mulch beds. I love it.

Excellent Product
I purchased this trimmer at the beginning of summer and have used it several times. The trimmer has performed great. Trims well, uses little line and handles satisfactorily. Can trim entire yard and have battery left.

Great string trimmer for maintaining a very big ye
This string trimmer handles my unique task well - I have 7.5 acres of yard! I use this string trimmer to clean up around trees and other obstacles that the mower just cannot quite get. I like the bump-feed operation of the string head. Reloading the head is super easy with standard string that's easy to find. The trimmer has a power-boost button to run in a extra high speed in case you run into tough weeds. The 40V battery is compatible with many other tools. The trimmer is very sturdy and I really love it.
