Build quality is really solid, and it's great that it's properly calibrated before it came out. Text is really crisp and clear, colors are OLED good. I was wondering if 4K would be overkill for a 15.6" monitor (it's higher DPI than my M1 Pro). The UI is around the same size as the "more space" option on my 16" M1 Pro (upscaled 2056x1329) which is perfect actually.It looks great connected to the thunderbolt 4 USB-C port on my laptop, though it will drain battery if not plugged in. Every portable OLED monitor does this however, and least there's a battery that'll last a few hours if you don't want to fuss with a second cable. Past that the brightness either needs to be low or you'll start glitching it out / have it shut down due to not getting enough power, but that's every monitor of this class. I haven't tried the HDMI connection yet. Steam deck looks gorgeous hooked up to it directly via USB-C.I have a 140w wall charger with a magsafe and a usb-c cable in it so that's not a huge deal (I can charge something else that needs it while the monitor is on battery). If the charging is a dealbreaker go with a 4k@60 portable IPS. You can get them a lot cheaper, and some even in 16:10 aspect ratio.Touch controls seem to single point on macOS, but I didn't really get it for that and it's convenient using the on screen menu with them.The screen is VERY glossy, more than my M1 Pro, so if you're in a high contrast bright environment that could be obnoxious. I would have traded a little pop for less reflections.The cover is a bit meh. The plastic is very secure once it's on, but the cut outs cover some of the labeling on the monitor. The actual mechanism for having it be a stand feels very secure, but isn't adjustable. The foldable side doesn't really stick strongly onto the monitor - I'll be slipping it in a sleeve in a messenger bag most of the time, but I wouldn't toss it into a backpack. YMMV on how much of an issue that is.I compared this against the only 3k@120 OLED (16:10 aspect ratio, same charging situation) portable monitor. On paper that was a win, but I ended up sticking with this monitor. I was getting some horizontal glitches on the 3k, there was visible banding in gradients, the pattern at the "Clock and phase" page of Lagom LCD test had strong vertical lines in it vs looking what the miniLED on my M1 Pro looked like, and getting the UI to be around the same size as my "more space" option led to the text being blurry. At default resolution (or just bumped up to HiDPI 1600x1000 vs 1440x900) the 3k one looked great, and colors were accurate enough for casual use.
