The Nikko Tire Pressure Wireless Monitoring system - was shipped quickly and arrived well packaged.

The Unit appears to be well made. And setup was super easy - you just insert the included batteries into the sensor caps and screw them onto the existing wheel valve stems.

I was able to get sensor readings from all four sensors with no problem from inside the car. The sensor caps - weigh 11grams.

My major complaint - which is why I returned the unit - was the lack of accuracy of the sensor caps.

The manual states that the sensor caps are accurate to +/- 0.5 psi.
Using two separate digital tire gauges that I have (which I know are correct & match readings) - I found out that 3 of sensor caps were Low by 4psi & one sensor was off by 5psi. Thats a little to far off the mark for me so I sent them back.

I purchased this item and recieved it in a timely manner. I have not used it yet on the road. Purchased it for a small RV trailer for trip and had to cancel the trip. I did install the wheel sensors to check if they worked and they did. I don't belive the sensors are as accurate as advertised, but that is OK for me as I just want to know if I have a tire losing presure so I can stop and check it. I have lost to many tires not knowing they were losing pressure.
