While the spools may be "free" they do charge you for postage and processing. The spools are small and the line is not all that tough. It takes me about 2 spools to trim my yard and my yard is not all that large. The Worx trimmer is a good piece of equipment. It is light weight and has plenty of power and the battery stays charged for a long time. I just wish they had a better design for the spools and more durable line. It is frustrating to have to stop frequently to rethread the spools or to replace them.
My grandson was so happy when he walked in to see I had gotten 12 new spools of line for the trimmer, he said "look Mom! It's a Party!!! as he was holding the package. He loves my worx trimmer.
I had a gas operated weed eat which was heavy and and always breaking down . One Saturday morning I was watching a segment about the work GT 2.0 with all the conveniences it had to offer. Being I already own several work products, I decided to purchase the GT 2.0... It's the best . light weight and adjustable to do whatever it is you want to do around the home. I would recommend this product because it's durable and saves time and money.No more extension cords, no more running out of gas. It works well when own a worx GT 2.0
