Query: Doesn't work right out of hte box

I bought this unit to monitor the temperature in my garage. I have wasted a lot of time trying to get the remote sensor to work without success. The trouble shooting guide should go ahead and tell you that there is a good chance that this unit simply will not work so give up and save your time. After reading several reviews it seems that buying this unit is a large gamble. It works for a few and doesn't work for most. It probably cost 25 cents to make, so they can afford 75% of the units coming back and still make a profit. If you enjoy gambling on the long shot this unit is for you. If you want a no hassle thermometer avoid this unit.
