All I had to hear was communicates to your cell phone or tablet. Just as you can be concerned about the quality of points & condensers the same can be true of aftermarket electronics. Case point; sone people love Petronix others haven’t had a good experience with it. I have a Prestolite points distributor in my old marine 4.3 Chevy V6, and at one time thought of changing it to the Petronix but decided to leave it with points. I usually get 5/6 seasons out of them before I replace them. I check dwell & timing at the start of each season & look at them to check for wear. I also have a spare points plate & centrifugal advance springs. The old tech works but it needs some not a lot of maintenance. However there are no electronic mystery boxes that when they fail leave you stranded with no warning. With a breaker points system there is warning that it needs replacement usually. That said OEM electronic ignition is usually very reliable.
