Looked to be just what I needed. Use cordlessly on the lawn around the pool and with a cord if needs be in other areas or if it was running out of grunt. Already have a Ryobi cordless blower and very happy. This trimmer has an automatic line feed as against bump feed. Idea sounds good but could not find anywhere an explanation of how it actually worked. Disappointed that the 18 Volt Lithium Ion battery was only 1.5Ah where my Ryobi blower's 18 Volt Lithium Ion battery is a much bigger 4.0Ah. Get the feeling that this might be yesterday's product sold today. Good product for maintaining domestic lawn edges. Would get something else for more serious work.

Seeing about 50/50 for/against in reviews I read prior to buying, I was dubious. Bought one anyway, from Bunnings, $99 without batteries. I did a least 10 minutes trimming with a small LiIon battery, it still has charge left. Quiet, smooth, instant on, instant off, cuts grass - every thing I need (for a small yard).

I was replacing Chinese petrol model, that was running very average. My brother told me he loved his Ryobi 18v, so I brought one. I already had the drill, saw, earmuffs, batteries. It take forever to cut though grass and edging takes even longer. I've gone back to petrol which I'll replace soon.
Cheap
It doesn't cut the grass

I have 200 meter path both side + 350 meter + of fence and house 1 18v 4ah battery and it did it all on one battery simple and easy to use as the manual like all Ryobi manuals are low on info like how dose the auto feed work you say who needs to know well it easier then using the manual button on the spool when auto not enough it extends automatically when it stop spinning so just stop and go 3 times and it reedy to go not in manual
light reedy to go is secons grate for mantained lawn not back yard over groths
manual and lack of good info like how long running time on battery how the auto line feed works

This one is a great little line trimmer. I brought it from Bunnings, without the battery, as I already have the drill set, and jigsaw. I will be buying the 4Ah 2 battery pack at some stage, but even with the 1,5Ah ones I have, it lasted long enough to trim the edges on my driveway, and gutter, along the path to the mailbox, and around the front garden beds. I'm very pleased with my new trimmer
inexpensive, easy to start, just press the button
Probably would need the 4Ah battery pack

I bought this product today, got about 10 mins of light work out of the battery life before it stopped working. Sure it doesn't fade - it just stops! I am completely underwhelmed and unsatisfied with this product that I will never go near this or another rechargeable trimmer again. Where on the box is it stated that a charge will last 15 or less minutes? And my trimming involved a lot of stop /starting so in net terms the trimmer probably actually worked for about 6-7 mins . It is very reasonable, considering all the battery hype on the box, that it would last a lot longer than that. Cannot speak lowly enough about this product and I will be returning it to Bunnings tomorrow.
Works for 10 mins
Cannot work for longer than 10 mins

Being an over 60 gardener I was struggling with the standard petrol and pull start trimmer. My husband bought the Ryobi 18V Drill so I decided to buy the Ryobi 18V One+ Line Trimmer as he already had the batteries. What a little beauty, so light, always ready to go. We have a 600sqm property which is on a corner which means extra footpath to trim and the battery covers all this area. For my needs it is the best thing I have used in a long time.
Inexpensive and light to handle.
The only negative is the safety switch which has to be held down along with the 'on' trigger. This button tends to hurt my fingers, so I have to think of a better way to hold the safety switch in.
