First, and this is not a criticism, it is essential to read the instructions and follow carefully the installation procedure. Unfortunately, there is nowhere stated that the system usually needs roughly 24 hours without any manipulation to synchronize the first time.
What I like least in WMH90 is the readability of the display: even pushing the contrast, it can be reduced by glare and therefore, we must find the right location. In addition, and for me it is unpleasant, the alternative display data in three phases is not configurable. Their interpretation therefore requires some effort.
Apart from that, no surprises.
However, I had the opportunity to put the receiver into "competition" for a week with Météo-France receiver. In the forecasts, it is doing much better.
So if it again, I think I will not rephrase the WMH90.
