My friend James (who is, by my reckoning, a heterosexual man) loves the Roomba he got for Christmas. It seems to fit into the stereotypical "modern cave man" lifestyle so well. Also, it's sort of cute and anthropomorphic.

Those mousetraps that don't kill the mouse are awesome. When my father's house was infested when I was a kid, we got a bunch of them. It made the infestation a lot easier to deal with, since you not only didn't have to deal with corpses, but you also got the little "squee" moment of joy releasing them into the wild. Where wild = local park.

While my mom doesn't ask for, and my father doesn't buy for her, any cleaning supplies, she usually expresses her want of a clean house more-so than my dad. Obviously, women still do the brunt of domestic chores, so it might make sense that Mom would be joyous in receiving a gift that makes cleaning easier (in reference to the non-sociological example)... as sad as it is.

I myself have come across the fact that women do not welcome useful gifts like a set of dishes and so on. However, there are things that are useful to everyone. I do not know of a single person who would have a negative attitude towards modern cleaning gadgets. Here's a look at the description in this article - https://swaay.com/6-steam-mops-to-clean-your-tile-floor I myself would not refuse such a gift. I hate doing my own cleaning.

Now it is quite difficult to open your own store, so it is better to sell products on a ready-made platform, where you only need to create your page and place there the goods for sale. In addition, it is easier to find a target customer who will be looking for your product. I myself sell through ebay, it is the most effective now. By the way, if you are interested, here is ebay customer service and you can find how to contact them. It helped me to clarify the details of product placement and so on. Good luck!
