Ryobi also loads this string trimmer with convenient features like the 11-13 in. adjustable string width for ultimate cut control. The 90° pivoting head swings out for easy walk-behind edging, and the charger has your battery fully recharged in under 2 hours. Plus, this string trimmer accepts the Connexion Attachment System.

Rated 4.0 out of 5.0 by Very Pleased so far Took it for it's maiden voyage today. Very impressed so far. I have a 1/3 acre in a rural area and admittedly the weeds around the edges of the property were gargantuan! So it was a good hard test for the unit...we're taking monster dandelion stocks several feet high in some places! I was able to do the entire property on one charge with power to spare. And there was always plenty of power to chop even the weeds that were becoming small trees! Nit picky stuff: I find the whole foot pedal switch to edging thing very finicky and i wish the string spool would last a little longer but I did find the string line quite easy and fast to replace.

Rated 3.0 out of 5.0 by Buy the Lithium Ryobi Trimmer Instead I've used this unit for about half the summer and got frustrated by the string line not advancing like it should. I bit the bullet and bought the lithium battery Ryobi trimmer with bump & feed. What a difference in POWER, BATTERY LIFE and STRING FEED. Unfortunately don't bother with this one, spend the extra $50 on the other unit! August 26, 2015
Rated 2.0 out of 5.0 by Had to return for a refund :-( I was excited to get this product as I liked how it was built and the fact it was a 40v LIon cordless. Seemed to work pretty good... at first. Then I tried the edge trimmer setting. I have a 24x20 lawn. I had to disassemble the wire feed and re-thread it at least a dozen times to edge trim around the lawn. The wire kept breaking off inside the spool. On top of that, the motor head was quite loose and wobbly on that setting. Finally, no screws came with it to secure the wire shield ... had to use some of my own. After I experienced this problem and before I returned it, I did some internet research only to discover I'm not the only one that has had this issue. At least Home Depot makes no bones about returning a product. May 13, 2015
Rated 5.0 out of 5.0 by Ryobi string trimmer This is the best trimmer I have ever used. It works well as an edger. It is light weight. The thing I like most is the easy start. The battery pack is a bit tricky to get off but once you get the hang of it it is fine. I would recommend this over a gas trimmer. I have .25 acres and the charge lasts into the next time I need to trim. It does have a lot of plastic on it which concerns me but the warranty is good. I have the .080 string trimmer and is a 40 volt. Great product. June 30, 2014
Rated 4.0 out of 5.0 by Trimmer Used it once. No problems so far June 1, 2014
Rated 1.0 out of 5.0 by burn out trimmer Brought this uint back in june 2012 didnt really use it till 2013 and the motor burn out in mid july still on its original spool of string! Took it to a Home Depot recommended repair shop, that doesnt handle Ryobi gardening tools and they sent me to another shop, which is pretty far. The first thing they did was charge me $25.00 for diagnostics told them it was a burn motor but still had to pay it. The unit was sitting at their shop unit Nov before I got it back, guess I could get it ready for snow now, during this time I've been calling them and they kept telling me that its waiting for parts. This is my 2nd Ryobi trimmer first one had the same problem but it was a lower voltage unit, figure a 40V would be much better, Guess not! I would definitely not recomend this to anyone or any of the Ryobi warranties! November 29, 2013
Rated 5.0 out of 5.0 by A great product I have too many toys that have gas engines. That is why I went electric. I have 7 acres and that means a lot of edges. My first task was to clear our a 150 foot ditch out front. I have had this trimmer for a month now and I have used it on, what I consider, heavy weeds and grass. The battery does last 30 - 90 minutes depending on usage. It charges within 1.5 - 2 hours. The string is only 9 ft long so it can run out fast. You may want a backup spool even if you rewind your own. I now own two Ryobi products (the other a pressure washer) and I am very happy with the quality of engineering in these two products. I am impressed with the 3 year warranty and you can buy an extra year through Home Depot for $15. The plastic feels a little flimsy, but it has held up so far. The biggest issue is battery replacement costs. $129. But the batteries should last if you take care of them. July 23, 2013
Rated 5.0 out of 5.0 by LOVE my 40 volt trimmer I absolutely LOVE my new 40 volt trimmer, edger and leaf blower and I will never go back to using my gas or electric tools. I have a 3/4 acre yard and two batteries is more than enough to complete all of the required tasks......without having to deal with fuel or cords. VERY satisfied with these Ryobi tools.
