Product review (5 stars): A good value, quite easy setup.
I bought one of these to help monitor a friends house while they were on vacation for a month. I live in Fairbanks Alaska. A house can freeze up fast if the power goes out, causing thousands in damage. It was great peace of mind to be able to pick up my phone and find out the current temperature inside their house while I was gone.

I'm no technical whiz, but it too me less than an hour from when I pulled it out of the box to the point it was set up and I was monitoring the temps on my computer or phone.
