Review on 🚚 BELLACORP TPMS for Heavy Duty Dually Axle Pickup Hauling a Fifth Wheel, Trailer, Camper, Box Trailer, or Horse Trailer - Includes Ten (10) Sensors for Tire Pressure Monitoring System by Justin Albright

I installed the pressure sensors on the valve stems according to the instructions. On the way back (July 2019) 3 out of 4 valve stems broke and 2 of them started leaking. You can see one of the broken valve stems in the third picture. One of the leaks resulted in the catastrophic tire failure shown in the first image. Note that I knew nothing about leaking valve stems until the tire failed. There was no fear. I replaced the flat tire with a spare, but then noticed the second valve stem was leaking, so I had to tow the trailer to my destination ($650). The most frustrating thing is that I bought this product to avoid catastrophic tire failure and this damn product actually caused the catastrophic failure! Please note that I contacted the company before posting this review but they offered no assistance. I also asked them for additional technical support but they never responded. As a result of my use of this product, I had to sit on the side of a busy freeway for several hours, call a tow truck and change the tire with all the valve stems on. It appears that the weight of the sensors causes these valve stems to fail after a very short time, probably only a few thousand miles. Obviously, this product has not been adequately tested. To aggravate injury, DO NOT use the included charger to charge anything other than your device. Although it uses a standard micro USB connector, it does not meet the voltage standard and outputs 12 volts instead of the 5 volts provided. Connecting this charger to another rechargeable device will destroy it. Upon closer inspection, I see that the other 1 star reviewer (Bond) has the same rim markings as me (compare the Bond reviewer's picture to my third picture). Obviously heavy gauges wobble at high speed causing some valve stems to break. In the comments to this review, the company's owner claims that steel valve stems are the best. BELLACORP never claims that their product should only be used with steel valve stems. Before using their product my valve stems were not old and in good condition. Less than a year after installing this product, all of my valve stems failed. Also this product needs to be tested a lot more. In some cases, this product can cause an explosion, which can lead to an accident. I've been lucky. This is the worst product I have ever bought from Revain.
