ALongSong has provided us with a nice looking weather station and at first glance everything seems to be working as promised, nice and accurate. But the instructions don't help as they obviously haven't been tested on an uninitiated customer who saw them for the first time. My main problems have been dealing with more useful features, such as B. occasionally using the backlight in the dark and setting the time etc automatically via the radio signal (the whole point) rather than manually (easy), which wasn't so good. I walked it around the house with it trying to find a signal (flashing satellite dish) and the only place with a result (radiation lines emanating from the dish) stood by an open window and held it at arm's length for a couple minutes, until it stopped blinking. Luckily the sun was shining. I shouldn't have to do this. The case has six buttons that are mostly self-explanatory, with helpful callouts on the back of the case clarifying functions, and the instructions are mostly consistent; SET UP/MEM/RCC DOWN/T-ALERT/°C/°F PRESSURE CHANNEL ALERT BUT the instructions seem to list a seventh button which I can't find: SNOOZE/LIGHT. You'd think it's part of the ALARM functions, but not for me, and I tried following the instructions first, then other permutations that seemed worth trying. Nothing SNOOZE related worked. The remote sensor seems to work, but it's definitely not waterproof. I find this a bit strange for an "outdoor sensor", especially when the sensor for my much older station survived fifteen years outside on the north wall of the house next to a bathroom window. I wouldn't even consider putting the ALongSong outdoor sensor in that convenient location; Within a few weeks, it would fill up with tiny spiders and moisture. It's all a shame because it looks good and is easy to read when powered by USB, but on battery power it needs a light or flashlight and I want to know what's going on outside if I'm still there in the morning waking up snug and warm under the covers. Addendum August 3, 2023 The clock runs slow and loses about 5 seconds a day. That's fine if there's a signal to reset every night, but if it can't find the signal easily, like in my example, you'll soon notice that it's a few minutes slow! My very cheap watch goes to a second or two for a whole week, so there's no excuse for this watch from Alongsong.
