Using the Otter Cage is a breeze. First, find a suitable spot on your bike or other equipment. Then, use the two included stainless bolts to attach the cage firmly. When putting your water bottle in the cage, just gently press it into the arms of the cage, and it'll hold it tight. As for maintenance, it's pretty straightforward. Since it's made of 5052 alloy, it's durable. But you can give it a wipe with a clean cloth every now and then to keep it looking good. If you notice any issues, don't worry, as it has a lifetime warranty from Portland Design Works. Just contact them for assistance.
