I’ve been riding regularly for a little over a year. I got a pair of Garmin Rally power meters when they first came out a few months ago. At first the main reason was to be able to work on a weaker leg from a back injury. To get to 50/50 power. I’ve found however, the real time data helps me see what I’m doing, particularly on hills, and try a little harder. I’m 68 and have no pretensions of ever being really fast, but I continue to get better. Longer. And I think the pm provide a bit of incentive. And well, I like gadgets.
