Bought the 15.6" 550 nits OLED 4K portable monitor. Absolutely impressed. Works with iPad Pro etc. Super-fast shipping to India. My quickest ever international order (Ordered Monday night and delivered via FedEx on Friday!). Very very grateful to Shenzhen Weichensi Technology Co., Ltd. It turns out I've been using their 500+ nits 13.3" 4K HDR LCD monitor since ~2019!!!
