40V ATTACHMENT CAPABLE 15" STRING TRIMMER KIT is rated 4.7 out of 5 by 3655.
Rated 5 out of 5 by from Ability to add different tools I bought this because I have a Ryobi 40volt self propelled mower and love it. I like that I can add a tiller, or a tree saw and other attachments and that my mower and trimmer use the same battery.

Rated 1 out of 5 by from Didn’t work I used it once and it stopped working. I took it back and got the brushless one. Hopefully it will work more than once.

Rated 5 out of 5 by from Brush Trimmer Attachment I am absolutely stunned how well this bush trimmer performs. Attached to my 40v Ryobi string trimmer you would think it was gas with the ease of cut through inch plus monstrous weeds.

Rated 5 out of 5 by from 40V ATTACHMENT CAPABLE 15" STRING TRIMMER KIT I recently received this as a gift. I put it together, which had one hard step to attach 2 poles together. I had a charged battery from other Ryobi product and went out to give it a test. As it is currently winter, I do not have much to use it on at this time, but from what i tried it on, it worked excellently.

Rated 2 out of 5 by from QA on product This was a very disappointing purchase. It seems that QA on the trimmer attachment and shaft connector have not been done. For example, the attachment could not easily fit in the coupler and the string could not be threaded since the spool was frozen tight. It took 3 separate visits to the local Home Deport and on-shift Ryoli representative to resolve. Eventually, a disply model attachment was needed to replace my new one.
