You may be right with respect to my opinion. So far I've not tested the device. The only way I'd consider its purchase is if I were allowed to do a test, blinded, using a couple of bags, as described above by RCPrince.
I didn't state with absolute certainty that it wouldn't be effective.
By the way, thank you for posting to this thread. It is very helpful for the manufacturer to provide input.
