Product review (1 stars): Unit arrived with 2 major problems: 1) the DC ...
Unit arrived with 2 major problems:

1)  the DC adapter plug does not fit will, so if you even slightly move the receiver it will momentarily cut power causing a reboot

2)  one of the 3 sensors reads ~30 deg too low

I'm sending this back and will try again with another.

UPDATE: the 2nd unit sort of worked, but the service has been pretty much garbage for the last (App and web interface just plan not working).  Just got this from the company:

Dear Valued Customer:
Despite our planning for anticipated growth, a record-breaking holiday shopping season has caused a larger-than-expected influx of new AcuLink users.
Because of this, the experience of setting up and using the Internet and app-related functions of our weather stations failed to meet the expectations of some AcuLink users. This has been due to server stability issues that adversely affect the internet-related performance of your new weather product. Rest assured the causes of the issues have been identified and are in the process of being corrected. However, the fixes include upgrades to the server architecture, large migrations of data, as well as the restoration of historical information and charting features for a small percentage of users.
While we would like to tell you everything will be working immediately, we want to be 100% transparent. The process will take more time than wed like, but we are working around the clock to restore performance to levels you expect and deserve.
We apologize for any inconveniences this has caused. These issues will be resolved as soon as possible, and we will provide regular updates on our forum.
Thank you for your patience and continued support,

Jon Balicki
