    I bought this product blindly since there aren't many reviews available (I mainly relied on the reviews of the "sister" DW).

    Positives:
    Mainly used for work from home (permanently open 3 applications): it has served me well, it has a large real estate and it facilitates my work - it's a big step up from my previous 27-inch 1080p monitor.
    I personally like curved screens (aesthetically), but they have also been convenient for me in the past.
    The USB C is everything: it charges (and transfers sound, image, etc.) a 13-inch surface book, while also providing power to the webcam, so I saved on a docking station, cables, etc. It significantly reduced clutter on my desk.
    Good colors (I don't have high demands) and brightness.
    The presence of speakers is a positive (nothing extraordinary, but I'm thinking of connecting a TV box to use it as a television, see below).

    Negatives:
    The menu doesn't offer many customization options and I haven't found a calibration guide anywhere - I have adjusted it to my liking, but without any wow factor (of course, my expectations weren't for something like that, it's a VA Panel, not OLED).

    It's worth mentioning that during screen sharing via teams/zoom, you need to be careful because it displays in 21:9, so it requires some attention (I solve this with RIP) - this doesn't apply specifically to this monitor, but to all ultrawide monitors.

    Finally, the online purchase through the Dell Exclusive Store was excellent: I ordered it late in the afternoon and it arrived at my house the next day with free shipping.

    UPDATE: I also bought a Chromecast which works perfectly and I use it as a television (compatible with the remote's sound).
