Any easy out that you can drill out, certainly wasn'y worth puting in the hole in the first place. No matter what size you drilled it. Cheap tools like to round off things. Then you really have a problem. I buy big name normally, but I have a shop. I use middle quality on the trail. But I don't give a rats --- about a warrenty. I buy the ones that don't break if treated right. It doesn't matter what kind of warrenty you have when it fails. You still have that fastener to remove, and if it busted the first cheap wrench, it will likely break the second too. That is if it can get on the rounded head now.
