This series aims to showcase the best gaming controllers on the market with some thoughts on their design, performance and pricing. You can expect more of these such reviews in the future, so stay tuned! If there's anything you'd particularly like me to cover, let me know and I'll try to get around to it. Of course, I can only review controllers I own.
The newest entry in this series is the HoriPad Mini 64.
