I made the switch from a Acurite 5in1 to the 2902 at my home five months ago and so far I am very pleased with the unit. Not yet long enough to determine how will it will hold up, but I have had no issues. Its great to see the indoor readings reported along with the solar and UV values.
I do miss not having a mobile app, but the web site will scale to a mobile screen just fine. Also you cannot have additional sensors connected through the WiFi display unit.
I still have a 5in1 in another location and I am debating on replace it with the 2902. I am waiting on the Elite to come out and see what everyone thinks of it.
