DEEWAZ TPMS Solar Power with HD LCD Screen, Real-time Display 4 Tires' Pressure and Temperature (-40~80℃), Wireless Tire Pressure Monitoring System with 4pcs External Sensors (0~99PSI), 6 Alarm Modes

Having been EXTREMELY disappointed in a previous purchase of a similar device here on Amazon, (returned via Prime, no issues, of course- The one here: https://amzn.to/2EV7hML) I was not sure that any of these add-on tire pressure devices were going to work out. The one in the link I have pasted has a narrow display, unreadable in normal daylight in a vehicle, and, with a badly translated manual was not easy to set-up. Not sure why or how it got so many "good" reviews.I'd just purchased a 16 year old van for hauling of things that won't fit in the back of my other vehicle. Everything worked except for one intermittent light on the dash, that being the tire pressure warning. This made me worry when driving if there was a real problem or a possibly 16 year old sensor going bad. Sensors are not cheap to replace, and I don't know which one was dying so, an add-on system seemed to make sense.This one WORKS. The display is larger, it's VERY visible in daylight as you can see, and nicely lighted at night but not obnoxiously bright. It paired easily, and charged easily via USB for it's initial charge. The orange-ish display is pleasant, and the unit can be placed just about anywhere. I don't know about charge-life yet. It seems to have a standby sensor that blanks the display when not using the vehicle, then comes to life when it senses movement like a door opening that slightly rocks the van, or being picked up and moved. Not sure what it uses for this, but this will contribute to better charge/battery life for sure.Found one tire low on install, the one I suspected, and aired it up with a digitally controlled air compressor at a local gas station to 32 PSI. The display matched and changed appropriately from the lower reading of 27. Have driven two days now, slight changes in pressure and temp show with driving which is normal, and this tells me it's at least getting updates from the tire sensors frequently.No worries now driving with the original sensor light on the dash coming on, I'll be relying on this box to tell me the bigger story. The price of this unit on Amazon is less than having a bad sensor found and replaced on an older car and an inexpensive upgrade to a vehicle. Glad to have found it.

Had a few issue with tires gaining air pressure had to make few stops working great 👍
