I reviewed Gioteck’s WX4 - both wired and wireless versions - a few months ago on the site, having also used them personally for over a year prior to the article -where they received a saucy 8/10 ICE COOL rating - https://www.gamesfreezer.co.uk/2020/11/gioteck-controllers-review-wx-4-and-jc.html
Having received the new WX4 premium version – again, compatible with PS3, PC and Switch – the build quality, connectivity and battery life are mostly the same but there are differences here.
