I did a quick search here for "points" and couldn't find anything, so I thought I'd warn people who may be hoarding points on Ecowitt.com for their next purchase. Maybe this is old news, but just in case.
There is a message at the top of every page stating "Please use up your points within this year, as this site will close the sales function and transit to the shop.ecowitt.com, thank you." It's been quite a while since I've logged into the .com site, so I'm assuming that means the end of 2022.
Also, if going to ecowitt.com directly isn't working, try going to something else like the
About Us page. For me, going to the site directly just leads to a white screen with a thin blue loading bar at the top that does nothing, no matter which browser I use. Every page seems to be working except the home page.
