Well it seems Valve still has a QA issue with the left controller mini-stick. Only a couple of months after receiving a replacement for the same problem, my left stick started drifting backward (doesn’t recenter properly). Quite annoying when you fall off a building.
On the upside, Steam service is as great as the first time. They responded in 1 day and after 1 more issued an RMA notice.They are sending replacements before I need to return the current set and will forward a prepaid return label.
Pimax may be smaller but should at least consider how the big buys do things. Night and Day.
Hope 3rd time is a charm.
