I guess there will always be slight manufacturing problems, but it does amaze me that there's seemingly no QC at all.there are QC issues with some of them, a guy at work had to rma his as the dpad wasnt working properly and sounded like an old microswitch when pressing up.
It amazes me how major manufacturers struggle to get dpad/buttons right, yet a cheapo retro handheld can be rock solid...
It would have taken someone about 10 seconds to find the squeeky spring on the trigger and another 5 seconds to realise the dpad was way too soft.
Same with screen issue, DOA units and everything else inbetween. Many issues were reported when people started receiving their units.
Do Valve not have any QC team(s) to test units before they are sent out? Interesting it seems only the review units were tested to make sure there were no issues!
