To give Holy Stone credit, they have good customer service. I bought one of their crappier models when I was first exploring the quadcopter marketplace a few years ago. They did the usual thing of proactively emailing and asking for a review after a few days, but then actually replied to my email rant about quality control with suggestions to debug the issue. Finally, once I'd crashed it one too many times and destroyed it, they sent me a new drone free of charge. I suspect they're probably doing similar to anybody who leaves a bad rating in order to groom their listings. (Don't get me wrong - their customer service doesn't make up for their poor products. Never buy a drone with injection molded frames, since they're not serviceable. Carbon fiber with replaceable frame parts all the way.)
