Does What it is Supposed to...
Reasonably priced, easy to use, accurate with digits large enough to be read from 5ft away. What's not to like?

It meets my needs
I bought this for my bed room to monitor the change of condition. I would say this is a good buy because it has a large LED screen, easy and simple read, nice look, and good quality. This is also good for those people, like me, who don't like complicate instructions on small thing.

for the price it is fantastic
I live in CO and wanted a way of determining the outside temperature when I go to the mountains, especially in the winter. I own a new Toyota FJ Cruiser that did not have and external thermometer. I looked at a number of thermometers that would replace the rear view mirror or as a separately installed item. Some ran as much as $1000. This works perfectly and was less that $20.

Just what I was looking for!
I was looking for a simple temperature gauge to be able to tell the difference between indoor/outdoor temps and this has worked perfectly! This was incredibly simple to set up and install and has seemed to be quite accurate. I can read the numbers on the unit quite far away and have really valued being able to tell the temperature inside our house, as we do not have AC and are often unaware how warm the house gets in the sumer.

The only challenge I have had is that the cord from the unit to the outdoor sensor is much longer than I needed and there was nowhere to hide the extra cord - it would've been nice to have a spot on the back of the unit to wind any excess cord.

6 Years, 21,000 miles, still going strong
I can't begin to tell you the abuse I've subjected this product to.

1- Used it on my RV. Probe was outside from freezing to desert for 6000 miles.

2- Took it up to Alaska and back, 15,000 miles.

3- Used it to determine the temp. of my developing solution (very caustic chemicals).

4- Now it's being pecked by chickens in my brooder.

I seem to never replace batteries in this. I can only remember doing it twice in 6 years.

Buy this product. Have no worries. It truly is a 5-star product.
