@cinoclav figures the one time I actually have time to do 5he research, but I instinctively buy because all the others have only had like 3 inventory. Oh well, if they last an hour, that’s long enough for a workout, and then I’ll just recharge them before the next.
Mine showed up today. I plugged them in immediately, charged them up, and gave them a test run. Given @cinoclav sleuthing, I didn’t expect much, and didn’t get much. I was sure to start a timer. I got 45 minutes before it started complaining of low battery, but realistically, they’re uncomfortable enough that I think I’ll be done with them after my standard 30 minute workout.
