This is the worst product I have ever bought on amazon,I wish I could return it, I have gotten rid of packaging material,the spool you get with this product is useless plan on going to depot and buying a replacement spool and spending a additional twenty dollars,thats what I did,I thought I had the problem solved,now when I use it,it smells like it's burning,I should have listened to the other reviews.
