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.

Rated 5 out of 5 by from User-Friendly Cordless Trimmer! Recently bought this trimmer and it is a great tool to have at home. For a reasonable price, this trimmer works nicely with enough power to get it done. It was an easy installation and battery charges fast enough to work all day around.

Rated 5 out of 5 by from Great power Going from gas to battery powered was a great decision. Unit is a comfortable weight and easy to use. I just wish it had come with a shoulder strap!

Rated 5 out of 5 by from Great products ! I bought a 40V chain saw which had a lot of torque and sliced right through branches that had come down in the yard. I was so impressed I bought a 40 Volt String trimmer and a 40 volt blower as well!
