I found the Mares Loop Octopus to be very well-made and durable. The innovative design allows for a seamless transition between breathing on a single hose and both, thanks to the quick loop release system.

If you’re in the market for an octopus that can work well for single hose and double hose configurations, the Mares Loop Octopus is a solid choice.
Kevin Tan –
However, I wish it was priced lower, $550 is quite steep for an entry-level octopus.
