Maybe times have changed, but when going off a boat I was always told to hold the mask and the reg in my mouth with one hand and the octo and console with the other. Using that technique almost anything should hold an octo in place from a $.99 snorkel keeper to your $20.00 magnetic thing. I never had my octo slip off on entry nor become detached during a dive using the Scubapro device.
The reason I ask if you test it first is because some holders do not work with all regulators. For example the simple ball you stuff your mouthpiece to hold would not work with my Oceanic Delta octo because the mouthpiece was too soft and too long to insert. I couldn't do it and my OW instructor could not do it, his advice was buy a new mouthpiece, which contradicted his earlier advice that soft mouthpieces are better. At that point I knew he was full of crap. As a side note I did not even need a holder because my BC at the time had a specialized pocket to hold the octo. He was just trying to sell me more junk.
