I read the reviews on this product before making my purchase...some good, some not so good. When I first charged the battery (about 5 hours) and used the trimmer, I was disappointed. My fault. Then I charged the battery overnight and used the trimmer for about 30 minutes without taking my finger off the trigger. Not bad. Again...my fault. Then my wife used it and only pressed the trigger while she trimmed. She loves it and there were no issues with time restraints. We were able to trim out the entire area of our flower bed (about 20' by 20') with no issues at all. Then I trimmed for another 20 minutes using her technique. Great for trimming around pavers, walkways, and inside thick plant beds. This is a nice trimer, but the battery is definitely not a quick charge. Follow the instructions and it works well.
