3.8" LCD Car Indoor/Outdoor Digital Temperature w/ Clock - Grey (2 x LR44 / DC 9~16V)

Pros: Design is great, and looks exactly as photo. Build quality is very good, buttons feel solid and support fixed perfectly to my truck dashboard. Having out/in temperature at plain sight is great when you are with A/C for a long time.

Cons: None really, perhaps backlight could have a on/off swith, but it's not a con, just a suggestion.

Other: Great buy! If your car/truck didn't have an on-board computer it's a must have!

Pros: When car key is turned off it gives only clock. When you turn car key on the screen light turns on and puts on all the other functions - in/out temperature and battery voltage, which I find as very useful function. Length of cable for outside sensor is 2,2 m, but would still prefer at least 0,3 m more if you want to get it to proper place, otherwise you get wrong temperature because of engine/sun heat interference.

Cons: When car key is off, you can't see temperatures. It's a bit annoying, but it saves inside batteries. Price could be lower.

Other: A good product, I recommend it!
