In terms of longevity, a twisted trimmer line is recommended in most trimmer line reviews because it lasts the longest. The quiet operation makes it the best string trimmer line for neighborhoods, especially in the morning. Plus, it works well on common garden weeds. However, there are certain disadvantages. A twisted trimmer line can tangle itself when used because of the exterior shape, which can take gardeners some time to remove. Besides, the price is higher than average products. Overall, the effectiveness level should also be based on the usage purpose. Gardeners need to identify the specific weeds to choose the suitable type and volume for the trimmer line.
