Product review (4 stars): Hang It On The Wall Or Place It On The Counter
Like others have said, the temperature reading is accurate and the humidity is a bit lacking but adequate.  I like these devices because the are small enough to be unobtrusive in a room but big enough to see at a glance.  They have a stand on the back that will pop out for standing on a table or they can be hung on a wall by a nail.  i have them placed strategically around the house to balance my HVAC systems.
