I'd kick the bugger selling that!
Serious, (I'm the one selling the atlantis gear) the scrubber seals perfectly, and always has. The ones that don't seal, do that imo due to repetedly overtightning, not due construction failure.
The biggest difference between the dolphy and the atlantis scrubber is where the male p-port end goes into the CL. On the dolphy scrubber you can replace that male bit, on the atlantis you can't.
The inhale lung comes with an extra p-port.
Hoses and mouth piece not on the list.
Yeah, ask away...
