My husband has the Worx GT...it is an edger and a trimmer. He says it's not the most powerful one out there, but it uses a battery so it is lighter than a gas one and doesn't confine you the way an electric one does. He says it works great and does a good job of both...edging and trimming.
You can look it up online...I know he ordered it that way. Just a suggestion...good luck! (Way to think ahead for Father's Day!)
