Assembly and setup of the transmitter and receiver was easy. Functionality is as advertised and good. The app is a bit average and setting up on Weather Underground took some mucking around. Would be nice to be able to download or log data locally.
Arrived quickly. Easy to set up, space permitting. Logging the data online is pretty cool but getting it to post data online required a bit of trial and error as the instructions were a little vague :^)
