3.8" LCD Digital Thermometer + Voltage Measuring Bar for Vehicles

Pros: This unit switchable between inside temperature and outside temperature. It displays battery voltage via a real time display like you would get on a voltmeter, and a little three bar bar-graph. It has a frost alarm (short beep and visual led warning) and also an over/under voltage beep and LED. Input is 12 volts only. Build quality is good. The outside 'ice' warning is probably the most useful feature.

Cons: The difference between the outside temp reading and the inside reading was 2 degrees on my unit (with the outside probe beside the unit) - so this can hardly be described as accurate! The voltage display isn't 'damped' and any change in battery voltage will show up instantly on the display - can be a bit annoying. When you power the unit on, it defaults to display the inside temparature...shame it doesn't remember your preference as I prefer to know the outside temp.

Other: The back light is very nice. It is switchable (slide switch on the side) between blue and orange. The back light will stay illuminated the whole time power is applied to the unit. It's a nice little gimmick gadget I suppose. it's a bit expensive for what it is though. Shame the temperature reading is so inaccurate.

Pros: Changeable backlight color. Car powered backlight. Accurate temperature reading.

Cons: only in or out temp is displayed at the time, second display is actually for battery voltage so the voltage display takes double space but two temp readings are squeezed into one field. No internal battery - when car is powered off there is no temperature displayed Mounting plate does not fold out whole 90 degrees. Temperature display has leading zero (-05,1C).

Other: It can be better but does its job.

Pros: My car instrument panel isnt provided with a thermometer, and i was looking for something useful in winter for under-zero information. and just for curiosity too :) The bonus info is the battery level, very usevul due i use the car almost at night and this makes wear the battery very quickly. No clock: OK usually all cars already have it!

Cons: IMHO, it is a quite big to place. A "no lighs" switch would be useful too. I placed it in cable power source so the lighter plug was cut off, i think it is the usual way to mount it..

Other: Good item for the price.

Pros: Really good product with 2 functions. I was searching for this one and the price is good.
Easy to use, really simple.
It could be better build but i am satisfied!
The voltometer is accurate and it shows every change to the voltage quickly!

Cons: The thermometer seems like its slow and if i change quickly from in to out to in the temperature changes...
Rather than that the velcro is small and i dont think that it can hold it properly.

Other: Its a fairly good product.
It will do the job right.

Pros: This model comes with a thermometer screen in various colors that are changed by a side button. The installation in the car is very simple, exterior thermometer cable is long enough to pass it under the carpet of the car, and then paste it into the plate under the car, the rubber door does not cut the cable.

Cons: The quality of the thermometer outside is very bad, is spoiling to 30 days to install, staying fixed at 60 degrees, another defect is the poor quality of the power input jack, it is continually disconnecting due to vibration.

Other: At night it gives a more technology into the car with colored lights, which are permanently lit in the color you want, using the side button.

Other: It can be better but does its job.

Pros: Good product with temperatur and voltage functions. The price is good. Easy to use, really simple. The voltmeter seems accurate and quickly shows every change to the voltage. Two colored lights display, switcing by side button.

Cons: It could be better build. It doesn't remember your preference and shows inside temperatur when it comes on. A little short sensor cable. Would prefer to mount the sensor behind the front bumper.

Other: Can be better but good item for the price.

Pros: A nice light different types of light or without light duplicate keys for the passenger soft and responsive buttons Velcro fastening complete xD

Cons: The long interval between temperature measurements. The difference between the sensors, even if there might be a few degrees

Other: If you have nothing to close the hole in the dash paneli.i from the factory in your car do not have a temperature sensor, and you need to know the voltage in your car, then this unit is very good. Good price and production

Pros: - Very nice blue display - Measures the battery quite accurate - If you keep boh sensors close to each other, they indicate the same temperature after a few minutes. That would indicate the accuracy of the sensors I think

Cons: None I bought this when I had my AC mended, before this arrived the AC broke again, so now I can not feel the joy of seeing how hot it is outside whilst fresh inside. Ohhh the sadness. Perhaps I can send you my AC? They break it quicker here then they can fix it

Other: If you aheva somewhat older, basic car then these are the gadgets that upgrade your car in a cheap and elegant fashion.

Pros: is perfect, works great, is very easy to make work, good materials of fabrication, beautiful design, the price is also perfect es perfecto, te ayuda a cuidar el perfecto funcionamiento de la bateria de tu auto o moto

Cons: none, ninguna, el precio es muy bueno, la calidad tambien, asi que es para comprar sin pensarlo

Other: muy bueno, si tenes una moto , podes chequear a cada instante si funciona bien la carga de la bateria cuando estas viajando, tambien sirve para autos, muy bueno e indispensable
