I wouldn't think about the total recording time so much as the actual usage you'll get out of it. If based on typical usage, you could get even eighteen months out of it, then you're looking at around $5/month for a device to serve this purpose for you.
Is that worth it to you? Perhaps not. But plenty of us pay similar amounts of money for software subscriptions related to productivity, so it's not especially outlandish compared to paying for Standard Notes, Todoist, etc.
