Think I saw HD return is 180 days. Contact Green Mountain Products and they may be able to help you also.
I purchased the 48" and like that length.
The 48" included (2) 25' ropes
There are 21 chainsaw type cutting teeth spaced about two inches apart which alternate in cutting directions so you cut as you pull with each hand. The cut is smooth. Your weight is under the branch making cutting easier. You can can make it easy or hard.
I have cut 5.5",plan to cut larger.
Don't think so.
