Product review (4 stars): Good unit for the money.
This is a good little unit for the money if all you want to do is check the temperature and humidity in your room.  I recently put in a new heating system and wanted to see if all the rooms in the house were being heated equally. I purchased two of these, and compared them to a similar but more expensive unit I bought years ago at Radio Shack. All three units gave me the identical reading in each room, so I'd have to say they were consistent, and hopefully accurate. I've had them about a month now, and both are still providing readings without a problem. I have a feeling that these were made by the same company that made Radio Shack's as the case design is practically identical. However, the quality of the units are not identical which is probably why they are half the price. The case of these two units is of a much lighter plastic and the brightness of LCD readout panel is much darker than the Radio Shack unit that was twice the price. Nonetheless, as I said in my headline, it is a good basic unit for the money. If the two meters were made better AND had a button to light up the display for better readouts in dark rooms, I would have given it a higher rating.
