selling on Amazon

Hi! I recently started selling on Amazon and came across the concept of dynamic pricing. I've come across several dynamic repricing tools and am trying to figure out how to choose one that's truly effective. I'm curious, what criteria do you use when choosing such a tool? It's important to me that the system automatically raises or lowers prices without losing profit, takes competitors into account, and doesn't trigger Amazon's bans. Do you have any personal experience with specific dynamic repricing tools, and what advice would you give to someone new to this?
