SwiftPaws home unit and pulleys are made of highly durable material.
The pulleys are the very same ones that are sold with our commercial grade units.
The tethers that come with the unit are made to break-away for safety. If you find that the tethers are breaking too frequently you can tie a loop for the anchors with the same line you use to create the course.
We are confident that with proper care of the unit and pulleys the SwiftPaws home unit will give you years of fun.
We also offer a warranty which you can download here.
