Whats the deal with super cheap, highly rated drones that you can find no information about?

There are a lot of drones on amazon that are like 50-100$, with 4.8+ rating, and hundreds of reviews saying they work great.

But they’ll be brands and models that bring up literally 0 search results, like “Velcase s101”, or “TMYES EC110”. I can’t find any info on them.

I’d like to get a cheap, beginner drone as a gift. Most drones considered cheap and beginner friendly as recommended on this sub are 2-400$ though, i cant find anyone recommending these super cheap (but suspiciously well rated?) ones.

Are these drones garbage from china with astroturfed reviews or something?
