I could also spend $50 to replace both broken trimmers.
What's wrong? The battery powered trimmer, anemic from the start, just isn't holding power. I have no desire to keep it working. So, I'll chuck it. As for the other one, I need to hunt down the trimmer head to fix it. I might just do that anyway. Replacing the head should be simple. I found the little levers that broke, too, so maybe I'll just spend the $5. First, though, I need to find my model number.
