I've grown up with power tools and can easily recognize a no-name brand, so maybe my bias is showing. A big clue is that it is found on Amazon only and no other sites with reputable sales of power tools. Another clue is when the descriptions are broken English from a bad translation. There are all sorts of red flags that are obvious when you know to look for them. Even the brand name items are suspect for the simple fact they are listed on Amazon. I trust nothing with comingling inventory and other Amazon shenanigans. I'd trust Harbor Freight before anything purchased from Amazon
