VESAFE Universal Solar TPMS, Wireless Tire Pressure Monitoring System with 4 DIY External Cap Sensors(0-6Bar/0-87Psi), Real-time Display 4 Tires' Pressure and Temperautre. (Color Display)

This worked great on my small 5' x 10' cargo trailer that I pulled with my crew cab sized GMC Sierra 1500 pickup. No issue with the range. It actually saved my tire when the dry rotted stem stem cracked and the tire began to lose air. Had I not had this system, I would have kept on driving with a flat and most likely would have torn apart my tire since I did not even feel the tire going flat. The alarm went off indicating low pressure and I watched the pressure drop from 50 to 10 psi as I slowed down and pulled over on the interstate.My only issue is the ease of pushing the buttons. To turn the unit off, I have to fish around the arrow button to find just the right spot to depress to turn it off. But for the price and ease of operation, it was a great investment!

Bought one of these kits for my older Pilot a couple of years ago, and it has worked perfectly. I have no complaint.Easy to install and use, pre programmed sensors into the display. The display does not have to be charged other than the first time with light charging it since. Love having the display show each tire, its temperature and its PSI digitally, and a beep alarm if they are low, especially when starting out. I set mine at 2 pounds under so i know when I need to adjust.The quality of this over the couple of years with my older Pilot, is the reason I bought this same one when right after I had new tires put on our CRV and the TPMS failed, supposedly due to a bad battery in one tire, and the cost was going to be 80 dollars to fix it, I went this way and got another one for the CRV. This is better anyway, showing each tire's PSI and temperature instead of just a warning. So far this one is working perfectly as well. I was surprised at the quality, so far, and the fact hopefully they will continue to work as intended, hopefully for years. A good alternative to the onboard systems, especially if there is a failure that is expensive to repair.

This unit is easy to set up and accurately reports pressure at each tire. It operates by depressing the Schrader valve in the valve stem to expose the sensor to the pressure inside the tire. It is important to torque the sensors down so that no air leaks out and they provide a tool to help with this. I did not use the anti-theft locks that came with the sensors.One thing to note is that care should be taken not to over torque the sensors since it will damage the o-rings that seal around the valve stem. This happened to me and some of the o-rings got chewed up, resulting in pieces of the o-ring getting stuck in the valve stem which had to be extracted with a dental pick. When I emailed the company about this, they were very interested in solving the problem. They sent me a replacement with no hesitation - I had a very positive customer experience. thanks to Aileem at Safe-Auto.

Reads the pressure but I had a gray screen one that was a lot quicker to update. This one the spare tire has it's own high and low warning but it doesn't effect the spare. You have to set the rear tires in order to set the spare as a warning. So my spare only holds 50 and my rear tires hold 60 so if I set my low warning at 52 it would make the tpms light flash and beep saying the spare was low until I dropped the rear tires low to 45.All in all I'm going to send this one back and get another gray unit for my other vehicle.Update:So after having some issues with the color screen and the spare tire the seller was able to get with their team and fix the issue. I had already switched over to the gray screen that works great and I've had one unit for over a year and zero issues. And now have two of the gray units in two vehicles. These are the best universal tpms setups I've found. Never had a sensor fail either.

Lacking in simple features but works ok.Cons:Sometimes the update time is a bit long. I drove off once with a flat tire and it totally didn't register.Needs brightness control. Only one level, too bright at night, and too dim in the daylight.Does not turn off automatically. It has a sleep mode after about 15 minutes and it wakes up super easy, like if a leaf falls on the car or the wind blows. It's annoying having to hold a button for like 3-4 seconds every time I turn off the car.The display is polarized, so you can't see it while driving with sunglasses on.The instructions are crap mistranslations by people who don't speak a word of english.The multi-function buttons have no click or bumps or anything to tell where they are by feel. There's no way to tell if you're actually pushing it or not.Sometimes the sensors freeze/crash and you have to take the batteries out and put them back in to get them to come on again.For what it costs, it should have none of these simple issues.Pros: It works and seems reasonably accurate when compared to other pressure measuring tools.

Received unit and tried everything to make it work correctly. It did not. Contacted seller who tried to help once finally reached and we came to conclusion that the monitor was defective. Based on that, the seller immediately sent me a whole new one all the way from Hong Kong, sent it 3 day delivery and upon its arrival I hooked it up and it worked perfectly. I fired up the monitor first in the vehicle and then attached the sensors the tires. After a few miles, the pressures shown on the readout. They would change a little as one would drive but that is normal as the tires heat up.Also, the instructions were easy to follow and adjusting the alarm pressure was very easy also. The monitor will run off of solar as one drives but also has a usb/cigarette lighter wire in the event it is very low or dark and runs out of juice.Great customer service and nice product, even has a sticky pad to place on the dash under it which is removable.

I ordered this product from auto-safe on Amazon almost three years ago for our Class B RV. It's been going strong since then. One of the batteries in a tires sensor just went out a month ago- I called customer service for assistance in getting the battery cover off and was just blown away. The rep was extremely helpful and friendly, and has actually offered to ship 4 replacement batteries and the battery removal tool for free. Just amazing.

Install was supper easy, programming PSI and temperature highs and lows was straight forward. I didn’t have any trouble getting signals from the tires on my 38’ trailer to the unit. I have used this with the USB charger while in use so have not tested the solar charge feature but I am glad I purchased this system as it has turned out to be a great value purchase.

These do work as advertised, however there is one important thing to note.If you are in a colder climate you may want to wrap plumbers tape around the threads that seal the sensor (the ones you screw the sensor open to replace the battery). Colder weather may cause the o-ring to shrink slightly making it slightly less effective.Also you might look at the pad it comes with and wonder how the receiver stays put.... trust me it does, i have not had this unit move around at all during operation, even in bumpy or other conditions. Also i can say that the solar panel does work as intended, the unit has not needed to be plugged in since initially charged, which is a nice as noone like to have thier pressure gauge run out of power on them :)EditInitially had issues, but seller has been very helpful in resolving these problems, updated review rating to reflect customer service effort taken to resolve this issue.

Very happy with those. Great feeling to be able to monitor tire pressure on the RV. Works flawlessly.

I actually like the fact that it beeps when one or more tires is below a threshold pressure, so we no longer need to eyeball whether tires look under-pressure, which is not very accurate, and most importantly we're not driving around on under-inflated tires, which can seriously degrade their lives.In the Canadian cold winter, if we have a number of low-sunlight days in a row it may be necessary to actually charge it off USB, but I've only had to do that once this winter, in December the darkest month. After that the solar panel keeps the battery topped up really well. I can't believe I took this long to realize how beneficial such a system could be.

I have been using it for a week and so far I am happy for it. I wish there was a shut off button for it. Maybe there is but I can't find it. Anyways the solar keeps it charged and I have had nothing but overcast for the week. I can't get the wrench tool to fit behind and tighten the nuts so I just have them on like big valve caps. The reader is a lot smaller than I thought it would be. Here are some pictures taken with a $5 for size.
