I've previously tried a few other brand's offerings in the segment and had all but given up and gone back to using a separate octopus reg. Many other similar products rely on a flimsy schrader valve under the inflator buttons and they will fail regularly as a result.. My last one always got the baby treatment, washed in warm soapy water after every dive and it still used to jam on regularly.

The Zeagle Octo-Z instead uses a machined stainless steel pin, spring and o-ring and it hasn't let me down yet!
