I was thinking about drones since it looks kinda trendish but there is competition in this niche, also there are tons of products available to sell so i wouldn't simply pick a product without investigating everything.
Anyway, what's the proper way to make a product research? i don't have any particular passion so for me any product will be the same. I was searching bestselling products but i don't know if you should base your decision on this.
What do you think? is there a software or something to guide you?
