How do I ask a neighbor to return a long-borrowed item on time?

I lent a neighbor of mine whom I tutor (she is 6 minutes away) a food dehydrator for her baby (she likes the dehydrated bananas). That was about 3 months ago, and I meant to lend it to her for 2 or 3 weeks, because she was asking me to make (more) dried bananas and fruit for her babies. I just messaged her asking to have it back before she goes away again this month.

She isn't from the US. So, instead of making more bananas (and spending money on fruit and the electricity it takes to run the machine 6 hours daily, I lent it to her. She has only used it 6 times in 3 months. Ah, and she just returned some plastic food bins from me, from a looong time ago where I had made food for her to try. I'm not doing it anymore, because it seems to expect it now. I have had her and her family over at least 10 times, and I've been to eat at her house twice a year ago. Granted they have children and are busier, but they travel a lot, and I'm sure they could make the time.

When I borrow something--I return it right away as soon as possible. I don't take it for granted that I can return it when I want to.

My question was--Do you return borrowed items on time? But the AI we have here wants to word the titles on their own. I have already messaged the neighbor.
