BELLACORP Tire Pressure Monitoring System TPMS 6BU (6) Sensors for Truck, Bus RV, or Dually (Includes Free Repeater)

My final edit to update: Don't buy. This does work most of the time but it has a fatal flaw: if a sensor stops working, the readout apparently continues to report the last temp/pressure. I realize that's what happened this summer when a sensor failed. It happened again when a tire blew and the tread (or debris) knocked the sensor/valve stem off. I saw the pressure drop to 37 psi and was looking for a place to pull over to check when I realized it was on the rim...and still reading 37 psi--as it is right now, days later even though the sensor is in the weeds on I-81 somewhere. The whole reason I bought this was to alert me quickly to a tire problem on my trailer and it failed to do so because of a design flaw. The people I've dealt with at the seller are very nice but the product has some problems (see below) and one major weakness. I'll be looking elsewhere for another TPMS.*******Editing my review again to update. The company did send me a new sensor so I hope this will solve my problem. As I think I've said before, when the system works, which is most of the time, it works well and, in fact, alerted me to a brake overheating a few months back. Maybe expecting sensors to work 100% every time in this environment is unrealistic. I hope it continues to function in the future. I'm ok with unscrewing a sensor and reinstalling to reset it if that's the price I have to pay for coverage.********************************************Installed sensors on my full-size van and additional sensors on my 30' trailer (wheels half way back). Everything worked great after I FINALLY got the pressure and temp ranges set up correctly. I work in IT and am an engineer originally and have seldom been more frustrated trying to use their UI to follow directions. But eventually....Left on a 4,000 mile round trip. Within a few hours, one sensor stopped indicating. Beep, beep, beep. Alarmed, I stopped, removed it, then screwed it back on. Fixed!Before the trip was over, 5 of 6 sensors displayed the same behavior. At one point on the outbound leg, I drove into a rainstorm and 4 of 6 stopped indicating at one time. Most fixed themselves within an hour hour. I had to remove one or two and reinstall. Eventually all started to work again.One sensor (on the trailer) would stop indicating every few hours. Stopping, removing, and reinstalling always brought it back. I seldom went more than a few hours without one of them malfunctioning.I thought seriously about returning it. The combination of convoluted UI (DON'T lose the owner's manual!) and uneven reliability tried my patience. But when it was working, it seemed to function well and did what I wanted. I could always get malfunctioning sensors to work again with a quick stop and I stop every few hours anyway. So, reluctantly, I'm keeping it. It did, at the end of the day, provide the coverage/monitoring I wanted 95%+ of the time, and the peace of mind was worth a lot. I've lost tires on the van and the trailer numerous times over the years and wanted some early warning of any problems.But I can't recommend it. It strikes me as a product that's in final (beta) testing, relying on feedback from users to tweak the last problems. I'm sure the next version will be better. Or find another brand that's more reliable now.

I bought the 8 pressure monitoring kit to keep an eye on my truck and travel trailer while traveling. I bought based on reviews from others. I am satisfied but not sure if I would buy again if needed. I had a problem and called the company and the guy (owner possibly?) was very responsive and helped me get things going quickly and can say their customer service is top notch. However, when turning the device on, it takes several minutes for the first tire pressure starts showing up. You can't just check the pressure before leaving on a trip. It has to be spinning for a while before it starts working. Also, if it stops working or not even hooked up to the trailer, it shows pressure in the tires or last pressure reading available. To me, that isn't a good thing. I would have preferred to show live view of all tires and pressures at one time vs having to wait for each tire to show one at a time which takes a bit. It goes through each tire set up one at a time and starts over again after and nothing showing for sure it is reading live tire pressures. You can turn off trailer when not pulling which is nice to see only my truck when not pulling. This item does seem to work well, but expected more or better for the price.Update, I kept having one of my trailer tires leak down on a brand new tire and found it came from one of the sensors. The tiny O-ring came out and didn't realize it and caused me a flat tire after several hours of refilling tire. I have since had a couple more of the O-rings almost get lost and fell out upon removing these to check air before traveling. Would be nice to check air in tire without removing these and they don't tell you how much pressure is in tire until you get moving down the road a while before they pick up, so cannot simply check air by using this prior to a trip. This problem can cause more of an issue than not having them at all. At this point, I am not real satisfied in my purchase and these are not cheap either.

LIKE: Easy set up. They come pre-programmed for a dually and a tandem axle trailer which is what I have. Just put the numbered sensors on the tires as per the instructions and you're good to go.DISLIKE: The display and mounting hardware feel cheap. The display is very lightweight and just has a rinky-dink feel to it. I went to adjust the angle of the display and the little bracket that slides into the back of it from the suction cup mount just snapped right off. I contacted the manufacturer and they are sending out a replacment, but it just feels very flimsy.UPDATE: Well, I think the pictures speak for themselves. They apparently used the wrong type of compound for the suction cup. And you can see that the replacement clip warped from the heat. Doubt know how I'm gonna clean up this mess!!SUMMARY: I would not buy this again.

After doing a lot of research I purchased this product. It was very easy to set up and works very well. My RV and trailer are a combined total of 66 ft I never experienced a loss of signal. When I'm not pulling the trailer the trailer monitoring part of the unit can easily be turned on and off by simply pushing a couple of buttons. Of course I never read the instructions so I called customer service to ask how to turn that feature on and off. They answered the phone. Spoke English! And we're extremely helpful!. I was skeptical when I made this purchase because I have seen a lot of bad reviews about other products of this type. However I am very pleased with this one and would highly recommend it to anyone.
