Because of misleading terms like Ultra and Xtreme, you expect better.
With words like "extreme" and "ultra", you'd expect a better quality product... After just a few uses, my young Border Collie gave the lead a single bite and, of course, a hole appeared straight away, making it unusable... I sent a message to the supplier's customer service, but because of a "high volume of requests", I still haven't had a reply. It's really disappointing having to look for another solution now.
