Product "scaled to the moon"

Hi, I wanted to kindly ask - how do you determine if the product has been "scaled to the moon" or not? I'm exploring product A right now that solves a specific problem in kitchen space - I see on FB Ads that there are around 10 brands advertising the product with 1-2 being very agressive with significantly bigger budgets than I have. Is there a way to assess whether it makes sense to enter the market? Its not commodity product in a sense that its available everywhere though.
