I don't think it has anything to do with age. Lifeloc is attending some of these conferences/trade shows, and making progress in their development of the "marijuana breathalyzer." The CEO has demonstrated a very strategic effort, and has financed the entire R&D by utilizing existing cash flow, without borrowing or diluting the stock - which investors should applaud. They are very experienced in this field, and know the paths to regulatory approval vs. some of their competitors.
You can't make a press release without "material information." If you do, and continue to pump your stock without any substantial basis, you just set the company up for class action lawsuits by disgruntled shareholders when the stock gets pummeled. Companies use "Safe Harbor" statements in their releases, but they are not foolproof. Lifeloc has been very conservative in releasing any press releases, that's why I feel when they do have some positive material information to release, shareholders should be pleasantly rewarded.
Cannabix has had no income, and continues to dilute shareholder equity. Their stock has more than doubled in just a few short days - all on a stationary alcohol breathalyzer for offenders, much like Lifeloc's Sentinel, which has been in use for years... Lifeloc's RADAR device is lightyears ahead of Cannabix's new device, they just need to work out the biometrics in the RADAR system, and it will come to fruit.
I can feel the momentum building, and my opinion is that Lifeloc will come out on top, as will it's investors - which have been very, very patient.
