No vibration is a strange choice given that Nintendo and Sony went out of their way to make that much better in recent years.
Lack of trackpad is more understandable. Sony have had that for two generations now, and I’ve never really seen it used as anything other than a big Select button. I bounced off the Steam Controller simply because games designed for controllers feel much better with thumbsticks. If I want to play a mouse controlled game like Civ, I will use a mouse. Even from my sofa.
Half of them aren’t in China though. It’s dropshippers, so you still get your cheap death traps, but you get them in a few days, Amazon get their enormous cut, and they get to take no responsibility when it burns your house down.
