Tire Pressure Monitoring System Careud Tire Pressure Sensor TPMS Sensor RV Truck Bus with 6pcs External Sensors Real Time Monitoring Pressure and Temperature Large LCD Display (U901T 6 Tire)

2015 Sprinter 3500 RV (dually)1. Nice quality design. No extension needed for a 25ft RV2. Once charged, the battery lasts a long time. Still plenty of power after 5 day of usage3. Works for a dually without valve extension, but a pain to put them on/off because the inner wheels are tougher to reach. Not the product fault.4. Only three buttons, so not that difficult to set up, but not as straightforward. The good thing - you only need to do it once and you forget it!5. Love the replacement battery option6. Checked the air pressure a few times along the way, right on. Love the peace of mind7. Seller was very responsive when I had questions before purchase

Instructions are in "Chinese-English" and difficult to follow. Eventually I managed to configure each wheel unit. I noticed that the pressure reading on one wheel doesn't vary as the other 5 do as temperature changes. I may have to reconfigure that one. I haven't taken the RV out to see how the system performs, but I was able to test them by loosening each remote unit and, as the pressure dropped, the receiver responded with a noticeable alarm. The monitor is just big enough to read each wheel at the same time. I liked that better than the ones that cycle through each wheel.

Does not work properly. Extremely inaccurate and not easy to use

This TPMS is great, very easy to install(less than 30 minutes) and the display is easy to read. Programing of perimeters was easy. Having both tire pressure and temperature is great. Price was reasonable.

I bought this for a Class C Motorhome. Instructions could be much better but I finally got it installed. In all my years using electronic devices this has to be the worst. I never did get all the parameters I wanted but the units low pressure limit is 100 psi which is useless on a class c which runs 80 psi. Total dissatisfaction. I'm returning it.Follow up. After communicating with customer service I decided to give it another try because there are many features I like about it. In the end I did return it because of the difficulty workiing with the controller. It seems to me a menu which would drop down to submenus would be much easier but that is a personal opinion. I have to commend the customer service group. They were excellent.

One of the sensors does not operate correctly for temperature readings...read 87 degrees no matter what the ambient temperature. Tech support had me jumping thru hoops and now wants me to reset the unit to factory settings even though with the horrible instructions provided, it took me several hours to activate all 6 sensors...the whole shebang gets returned tomorrow.... I have had enough.

Installed these on my travel trailer and pick-up in about 15 minutes. They work great and are very accurate.The only issue I have with it is the monitor will not remain turned off. When I turn it off, it comes back on in a minute or so. That doesn't really bother me because the battery seems to stay charged forever.

UPDATE: After having the issues mentioned below, my husband reached out to the company via email. He was immediately told with no questions asked that a new sensor would be sent out...it was. After installation, it worked!! Hubby is happy with the service and the technology. Thank you to the company for backing your product without question.We just received this and my hubby (who is a very experienced mechanic) struggled with both the directions (written in very poor English) and getting the unit to work. In fact, he will be trying to reach out to the company tech support today. Once he got the unit to read all six tires which lasted less than 1/2 hour he now has one that won't read at all and another that reads sporadically. He thought the one sensor might need a new battery so he replaced that which did not help. Will be returning the unit if he can't get this resolved.
