Product review (4 stars): I got mine to Work!
Ok, so here are my two cents worth.  Yes, the online interface is clumsy, yes you have to fix the defaults on the phone app as listed in other comments, and yes I would still recommend it.  Here are my reasons:  1. Its cheap for what you are getting.  2. It works once you get past the not quite mature interface, 3. It is a simple tool for a simple job, 4. It was not very difficult to setup and the minor fix was easy once someone pointed it out online (its default settings cause some to get server errors).  Its online interface is clunky and non intuitive, but it gets the job done and can be understood once you play with it for a short while.  All in all, it does what I need, to monitor the temperature in a travel trailer for pets when I am not there.
