I don't understand the bad reviews

Do yourself a favor and buy from a reputable seller when your looking to add an extra NES Classic Controller to your home set-up, avoid being burned-out like other negative reviews with a knock-off product.

I'm not sure why their inability to read leads them to write a negative review about this product.

I was wary of buying a knock-off controller with all the poor reviews they had

Ignore the bad reviews.
