Ambient weather WS-2000 vs the Ambient weather-2902A/B review: Worth the extra money?

In this video I talk about the differences between the WS-2000 vs the WS-2902a. What perks with the ws 2000 makes it worth the extra 120-130 dollars? Also just a general review on the ws-2000! Thanks for watching! * recent update* you only can get the 2902b now as it’s an upgrade from the A model. It allows you to add sensors to it!!!
